305-350 TPI Intake

[Civichik05]

What would I need to change to convert a 350 to TPI, using the 305 TPI parts? Do the intakes still mount differently on the heads? I was thinking just find a 350 intake, and the 305 TPI FR's and injectors should be ok right? Thanks for any help in advance.

Already found out. You can use the TPI setup, and you have to replace the intake.

There was only one difference between the 305 and 350 TPI cars, and that was the injector size. 19 lb for the 305, and 22 lb for the 350 cars. TPI was designed for the 305 really.

no my question was the intake itself I know older pre TPI intakes mounted to the heads differently and the bolt holes don't line up between the 305 and 350. I just wasn't positive if it was the same for TPI Engines which it is.

all I take is a grinder to make the hole longer, then fill the rest in with rtv.

It wasnt a different between the 305/350s I recall it was they went to center bolt valve cover from the perimeter bolt, they just the angle of the 2 inner intake bolts on each side.
