I can get a 350 from an 87 IROC to go into my 91 305 GTA. What will i need besides the motor. Wil i have to get the 350 computer and wiring harness or can the 305 one do with a chip or something. Thats an expense i forgot about. So in other words, besdies the motor itself, what else will i need for this swap.

This should make my car more than half a second faster for next year at the f-body versus mustang shootout! You must help, because there are hardly any stock mustangs on this island, they are all modded, so i'll need a modded 350 baby!

 

has anyone switched from a 305TPI to a 350TPI before? any help would be appreiciated.

 

get the computer and harness, it will make the swap easier by a factor of 23

 

I want to put the intake from my 305 on the 350, so would that help. someone on another site told me it was all the same except i need a new PROM. IS that right? Please there are two of us after the same motor so i need to know if its any good to me...

 

Guess who might be getting an LT1 donor car justin, beat to jesus but motor perfect with <100,00kms with a 6-speed, it;'ll take me a while to get it in if i get it, but man o man, cant wait to find out the asking price on it

 

thats sweet! i'll give you the LG4 straight up trade! whatdo you say ?ahaha

Seriously though, would you sell me that standard tranny? and i'll give you a partial trade with a 700R4. I really want a 6 speed. What the motor out of?

 

so if i put the 305 speed density intake on the 350, would i still need the wiring harness and computer or could i do without.

 

Have you compared the horse power between yours and his. There might not be that big of a differenece. https://www.thirdgen.org/newdesign/tech/techdb.shtml Also does this person have anything done to teh 350? What do you want to do to it and what kind of results are you looking to get???

 

If you are going from MAF to SD you will need harness and PROM. SD to SD is a PROM upgrade.

i am aware the is roughly 30 more hp, which by uitself wouldn't be worth a swap, but since i want a 350 to even further modify, its better than doing it to a 305. He has had the heads ported and a bigger cam. What i have done to my 305 could easily be swapped on the 350(headers and stuff). PLans for the car is to run 13's easy and with some luck maybe even 12's

 

Not luck, what you need to dip into the 12's is a supercharcher!!! That'll get you there lickity split!
