I have two numbers off my TPI intake man. 10088016 and 1143539. Im trying to find out if it came off a 305 or 350? Can anyone here help? or point me in the right direction?

 

Doesnt matter as all tpi intakes are the same. Now the bolt pattern may be different for the head switch in 87 and also vette intakes had egr come in at a different spot

 

Idk about the numbers but the only differences in tpi intakes I know of are the maf/ speed density year difference, older ones had a cold start injector which was done away with in the speed density ones. Then the injector size and possibly the FPR but don't quite me on that last one, I used a 305 maf setup and bought the block off plates to convert it to speed density and nix the cold start, and I just bought a reman set of ford injectors because the originals were all mix and match set, oh and a BBK adjustable fuel pressure regulator. Currently the setup is on my new motor I haven't had any issues on the intake portion, you can make any intake work really it just may need more work than others.

 

The plates are for the EGR and cold start delete ; not to convert to SD (MAP)
'89 TPI was a MAF setup with no cold start

 

No egr delete, it was the billet injector plate and the plug for the rail, I just refer to it as the map style, my own personal misinformation
