That is good to hear. My 66 Impala only has a 283 but I recently built it 30 over with about the same cam, 500 lift only difference. I got a smoking deal on some rebuilt 80s 305 H.O. heads that gave me bigger valves and higher compression, not to mention OEM hardened valve seats. I still run the ram horn manifolds and that allows for the stock alternator mounting. I did block off that down draft tube and went with a PVC setup. I'd like to see if you incorporate a PVC and still keep those valve covers.

Back in the 70’s I had a ‘68 Camaro SS with the 327 and 2:73 rear end. It was white with a black nose stripe, black vinyl roof and red interior. The tires were BFG T/A’s on aluminum slotted wheels. After graduating from college, my buddy and I drove it from Hamilton to Vancouver to LA and back in the span of 6 weeks. We didn’t have one hiccup with that car. I sold it in the early ‘80’s and have regretted it ever since.

We had a 66 impala SS with all original papers. It was listed as 275hp with single exhaust, if dual exhaust it was 300hp. Using this paperwork and many other sources this engine had the "300hp" cam which would later be used in the l48 350's of the 70's.

In 1962 I ordered a new Impala with a 300 hp 327 and 4 speed. I ran at the local drag strip every Sunday. It came with 2.5 inch exhaust with the rams horns manifolds and I had open exhaust dumps welded on. I put on a set of Hedman headers and made no difference at all in et's or mph. Some rams horn manifolds were smaller though. I won 23 trophies with that car and it was legally stock and had a blast with it!

@@BuzzLOLOL It got the 302 which was is based off an even hotter 327 the L74, just with a 283 crank. The L79 would be stroked and became the L46 350/350 exclusive the Corvette. That Chevy parts bin isn't as big as most often think. The L79 was the solid lifter short block and heads(2.02) with a decent cam vs the plebeian standard 4bbl cam. The challenge Chevy had was the SBC didn't have great flowing heads so they leaned on the cams so rougher running more stall prone mills if they wanted power. You don't see the first decent factory head until '71 on the LT1 350. Perhaps over looked is that it introduced the 350 exclusive to the SS350 Camaro in '67, that stroke and more importantly the extra torque was something felt in every test drive. So much that with similar gearing it matched the 302 in acceleration at least until the headers and slicks went on.

@@Dayandcounting - The first Chevy 302" were the '301's we made by overboring a 1950's 283... The small, light. streamlined '67 Camaro really should have had the L79 as its top engine option... but that would have been too much power/speed too soon for GM... and the rear suspension would have had to been better from the start... also, like the Fiero, Camaro was prolly first sold to GM as an 'economy' car... LOL! Chevy heads didn't flow bad for the time... a little 327 with 4 bbl. carb., base level cam, and 10:1 made 300 HP... everybody else back then needed lots more cubes to make 300 HP... Chevy's base 1.94" intake valves were bigger than Pontiac's hyper 1.92" intake valves... eventually everybody's small blocks got up to Chevy's hyper 2.02"/1.60" 'Fuely' valve sizes... except the Ford Windsor engines...

The rear springs ripped off the frame about the time he dropped the clutch in 3rd gear, rolling about 40-50mph. What ensued was the longest, most amusing crash I’ve been involved in. Seems like it took a full minute for it to spin all the way around in two lanes and median, grass flying around, him cursing and fighting that massive steering wheel

Lots of 327 hype .reality there not that good, A plain 350 built can get more power and they can't touch a 383 or 406 no matter what go fast parts you put in them, if the same parts go in something with a bigger bore and longer stroke , its not going to come to close or compare

I know that I would get some weird looks sometimes when I'd tell people that it had the small journal 327 in it. It had a front sump oil pan too! It took its own special oil pump, pick up tube and oil pump drive because of the front sump oil pan. Wish I still had it! My brother wishes that he would have kept it too!!

My first car/truck was an '83 S-15 GMC pickup. It had a 2.8L V6 in it. It let go one day after about 173K miles, and the truck just sat. A buddy of mine had a 327 sitting around out of his dad's long-gone Corvette (not sure what year since I was just a kid, and not sure what trans it was bolted to). We decided to force it into my old truck one day. It took a couple of high school summer weeks, but we got it running pretty good. The fun didn't last too long. After a few pulls and his dad helping us tune the carb (I think it was a 4bbl Edelbrock) , our home-shop mods to the drive shaft let go. The fun ended there, but what memories. Knowing what I know now, with the resources I have....that would/could have been sooo much more fun....and probably trouble, for a youngster. LOL

@hotpuppy1 2 жыл бұрын

One thing to note to the owner: find a set of plug heat shields to use with the manifolds. Those log manifolds will cook the plug boots without them---I know from experience. Vette rams horns with angle dumps might fit and give better performance. They have 2.5 inch outlets. Those old Impalas used rams horns so they should fit OK. Older blocks had the road draft tube at the back of the block next to the distributor. California emissions had PVC valve mounted in that hole instead of the road draft tube. "Later" (relative term) blocks lost the hole in the rear and needed the hole on the valve cover. Frequently people would put a freeze plug in the road draft hole on early blocks and use vented valve covers. Oil fill and breather intake stayed on the front of the intake until 1969 when the inlet went to the opposite valve cover. That made sure that the vapors were pulled from one side of the engine to the other.

I wonder if a set of 2 1/2" "ram's horns" manifolds would have done better than the stock manifolds you used. I'm pretty sure the 2 1/2" were used on the Corvettes for quite a few years

I agree. The rams horns, especially the 2 1/2" Corvettes flowed better than the later manifolds. In fact, his 66 Impala would have had rams horns on it from the factory.

I agree with everyone that's mentioned the bigger set of rams horn manifolds, and 66 should've been stock for that year. They flow whole lot better than the log manifolds will ever be able to. Plus Jegs has even bigger ones that are very close to original factory set as far as looks go, but have bigger runners. I don't remember seeing the dump pipe off the back of the intake manifold that vents oil vapor an such from those blocks. That engine was rated at 275 @ 4800 rpms, and 355 lbs torque @ 2800 rpm with a 750 cfm spread bore quadrajet carburetor on it. It's a wonder that little mouse motor could move that lead sled as well as it does, but then it does have 80 lbs of torque more than it has horse power.

@danielsacks7152 2 жыл бұрын

Mopar big blocks other than some trucks never used exhaust gaskets either. Best way to go! Surface them flat, use a SMALL amount of rtv and antiseize the bolts with hardened washers and torque to NO more than 15ftlb. No warping, the hotter manifolds can move relative to the heads and metal to metal heat transfer. I know pro builders that Surface headers, cut the bars between the ports and toss the gaskets. (Copper or SS does work well on imperfect flatness tho) First thing you did on a big block international plowing snow! Unless you liked changing 3 sets a year and a huge pile of scrap cast iron in the shop! (The next two were to drill out the jets and crank the timing around to where it ran good!) Amazing how many stubborn people can't wrap their heads around this and warp manifolds and twist off bolts trying to hold them.

@danielsacks7152 2 жыл бұрын

Also. I always use copper on headers and always use at least a 6" high quality piece of flexible exhaust just behind the headers. This is especially important with bigger diameter systems because the pipes are so rigid they torque the headers HARD and will take out gaskets and Crack header tubes from engine motion and expansion. My headers and gaskets have so far lasted 3x longer with my 3.5 to 4" system this way.
