Man that’s awesome! Makes me excited for my L31 build for my 3rd gen Pontiac lol. I think a good carb and some head work for a bigger cam is all I have left. So far on my future build “list” is: Aluminum intake, HEI distribution, long tube headers, forged flat top pistons, head work for whatever cam I choose, and a bigger stall for the 700r4 after it gets built. I have an Edelbrock 1406 right now I’ll start out with but I might switch out later on down the road for something a bit heftier

The L31 heads are underestimated and have great mixture motion and brake specific fuel consumption. As long as you don't eke out to much iron, they are a real advance on any other SBC grouped exhaust head. A factory Double Hump match mate.
@alertgasper7 ай бұрын
and that's a salient point you made--people focus on how much CFM a cylinder head port can move, but if the air/fuel mixture isn't homogeneous or the combustion chamber's shape gets in the way of flame front movement across the cylinder (assuming no pop-up/domed piston) then that head isn't going to make the power it should.

The problem with the Vortec heads, is that they are very thin castings, and they crack very easily. When Richard said they cut .030" off them, I almost cringed! I'm sure they are fine as long as they dont overheat. That's what makes them crack wide open right between the two center cylinders.

Just one small suggestion: I've heard swapping the Ram-Jet 350 cam into the stock Vortec 350 w/factory long-runner intake & "spider"-injection helps wake it up, and make a real stump-puller out of it... so you might want to consider that.

When you add Vortec heads to a flat tappet cam engine, do you have to worry about the valve springs that come with the Vortec? Possibly too stiff?

So what about a daily driver truck application? These mods did nothing in the lower rpm range where most trucks are driven. I’ve got a 95 gmc with the non vortec 5.7 and I do a little towing with it. I want to keep my rpm’s in the 2500 for fuel economy, but need a touch more torque. All the tests I see are awesome for racing applications where you have high rpm’s, but not very applicable when you’re building something for more practical use. It’s not something I have seen on here or engine masters and would like to see.
