I was very disappointed when I learned the L30 head did not receive the same development work as the L31 version. The L30 head is similar to the previous L03 other than the 8 bolt intake pattern and...

That's not much gain. You might see greater fuel economy with the new heads but it's hard to predict that. Ultimately if putting the engine together with parts you have gets the truck on the road...

7.9 is low and you're dealing with an old chamber design so fuel economy might be low. It would run but I'd keep an eye out for a smaller chamber version. Maybe someone has reasonably priced set...

I agree with Dave. The 882 heads will make it tough to get the compression ratio you want. It's not too hard to slot the center bolts in the manifold but it doesn't look pretty afterward. What...

Just go turbo. Even a mild cam makes power with forced induction.:laugh:

I have a 350 hp 327 copy cam in my truck and that's definitely not an EFI cam. It wasn't as easy to use with the original 1983 Camaro ecm but the 7427 was easy to tune. I wonder if the EFI friendly...

Comp's online cam selector doesn't show this cam for an EFI application but I think you'll be ok. It looks fairly mild. It's got less lift and duration than the Speed Pro cam in my '57 although the...

283 was a nice engine and very fuel efficient although it doesn't produce a ton of torque.

Knock sensor should match bore diameter as close as possible. A 3.8 / 3800 Buick engine is probably...
