The 4.3 CPI Engine is rated at 200HP!

I intsalled one in a '92 S10 that had the 160 HP 4.3 in it and trust me you dont want to run the CPI System they have a very expensive fuel injector in them and it gives alot of problems.

I went to a junk yard and pulled a TBI Intake manifold off of a 4.3 and installed it on the CPI block & heads and still kept all the TBI stuff that the S10 allready had.

I also had some edelbrock headers and a cat back system on it and a 14" K&N Air filter and that thing ran very good.

Alot of people thought i had a V8 in it

Here's a pic after the install.
