ok, so i am going to get a new engine, just have a few questions. i am planning on getting this engine, it is a 350h.o. my questions are. would i be able to use the computer off of my 305 and could i use the same throttle body and intake?

future engine?

the computer from the 305 won't work unless you put a chip in it for a 350 or a custom burnt which is what i believe you'll be needing to run this engine properly. the intake will work but you'll need bigger injectors since the 305 uses smaller injectors than the 350. other than that though most everything else should work fine. good luck.

Nope won't work, you need a vortec style intake.

the bolt angles are different on 87 and later heads and so on but i always thought the tpi intake bolted to vortecs but i could be wrong.

Yes, you can modify the vortec intake to bolt on but, the rectanglur ports on the intake is slightly longer (some say taller,) the heads will be sucking in air from that slight difference.

When I laid the stock TPI intake between my new fast burn alum heads , there was a gap of no less than a 1/4", I would clasify tha t as a huge leak.

I repeat you can only put a Vortec intake on vortec heads. No way around it unless you want to weld 1/2" of aluminum to the top of every port.

You can't do it. Vortec heads are different than centerbolt heads which you are referring to.

rgarcia63

The Heads I refer to are "Fast Burns," never said they weren't Votecs.
The head in the images below ia a GM Fast Burn Aluminum head P/N 12464298. As can be seen it has dual intake bolt patterns, as well as center, and rail valve cover bolt patterns.
I bought a Scroggins-Dickey High-Flow Vortec TPI baseplate (intake) P/N 12498060 to top it off.
GM Technical Note for the Fast Burn head:
Use intake manifold P/N 12496820, 12366573, 12496822, or 10051103 with the Fast Burn cylinder head.
These are all Vortec intakes. Which means that the Fast Burn head, incorporates the Vortec design.

I wasn't talking to you.

rgarcia63

Ok, my mistake.

ok so i can't use the stock intake, but would the motor mounts line up? or would i have to fab my own?

rgarcia63

Motor mounts should be same.

rgarcia63

Motor mounts should be same.

ME Leigh

Huh? What motor mounts? We are talking intake manifold here they bolt to the heads. THe motor mounts bolt to the frame and the side of the motor.
