Re: TBI vs Port Injected

This is a very interesting concept, which I will probably try. My only
question is that, if I do this with a stock 4.3 TBI manifold am I starting
with a sows ear? My guess is that I am. This manifold is a single plane
manifold with virtually no runners to the center cylinders and long
convoluted runners to the front and back cylinders. The most compelling
reason for converting to CPI may be to get a decent staring point for
manifold design.
The CPI seems like a good manifold.
I had a 93 Jimmy, 3.23 gears, 4L60E trans and 200HP 4.3L CPI (Only
model/year available with 200HP... all others were 190-195)
I added a K&N air filter, 180 thermostat, Premier Performance 6 in 1 chip,
3" cat back exhaust and Edelbrock headers.
Best 1/4 mile time was 13.97@ 95 MPH. I had a set of 295-50-15 BFG Radial
T/A's on the rear and could light them just by romping the go pedal from a
stop... no power brake required, and at WOT it would roast them on the 1-2
shift and get a good LONG chirp on the 2-3 shift at 70 MPH. Not sure what
it weighed, but it was a 2 door and I weigh 275-280. I also got 25 MPG on
the highway.
