Carb and TBI Question
« on: February 06, 2011, 01:44:48 PM »
Ok I just installed a NEW Jasper motor in the 85 Suburban. It is a 350 with a Edelbrock 4bbl. I have been having some issues with it. High ideal not wanting to work and thus making the choke not work eather. I have access to a TBI from a 87 burban and was thinking about a swap. My problem here is I have never done this and did not know if I need to swap the heads and the intake to make this work. Iam not wanting to do alot of extra work to the motor being it is all brand new minuse the carb. What do you all think? easy swap?
Thanks in advance:

No, not easy.

The first TBI systems could not handle much cam difference so that would have to be swapped. The heads are OK but the intake is very different between the two. You would have to also swap the whole wiring harness, fuel tanks and run all new fuel lines.

This is all not too bad if you have a complete donor but it's still a lot of work. You are better off going with either an aftermarkt EFI or just fix the carb you have. in my opinion.

Hope this helps
