If you get the LT4 AFRs, will they absolutely not work with the LT1s?

If this is the case, where can I get an LT4 intake?

Thanx dude.

Do you by chance know the LT1 runner size?

 

Phew I'm gona have a brain hemmorage if I try to remember that one. Shoot a PM to Injuneer. By the way I don't think you can port match to the gasket. Check it on both pieces before you do anything.

 

Sent you a PM.

 

I compared an LT1 and LT4 intake side-by-side and saw little or no difference. The LT4 ports are narrower at the top, but the location appears to be the same.

Mike, what year LT1 intake did you use for the comparo?

 

1995

 

'96-97, and some late '95 intakes have port shape, at flange, to replicate that of the LT4s. Earlier intakes had a crisp rectangular shape to them, unlike the LT4 intakes, or the intake ports of LT1/4 heads, of any years.

 

Mine had rectangular ports that are actually larger than the stock LT4 ports, which taper narrower at the top.
