Some of you guys are probably still trying to forget what a PITA I was back in 2013 when I first started messing with my TBI 4.3 in my '40 Ford Pickup. Well 9 years and 30 thousand miles later, I'm back. This time I'm putting a non TBI 350/290 Horse smallblock in the truck. This is a Chevrolet crate motor with 25K on it and ran fine with the Holley 4bbl that and Mallory unilite dist. that was on it. I have been converting all of the hardware on the engine to run my TBI.
I have installed an adapter and a rebuilt 350 throttle body equipped with an adjustable fuel pressure regulator onto the Edelbrock Performer manifold. I have installed a TBI distributor and I have a chip from a 1990 GMC 1500 4x4. I have installed a new TPS , MAP, ESC and IAC. The block has also been drilled and tapped to accept the knock sensor in the same location it was in on the V6.
My question this time is the camshaft... This engine has the following cam: .450 intake lift .460 exhaust lift 222 intake and exhaust duration at .050 and 114 degree lobe separation. The computer I have has a service number of 1227747 and the chip is ASDU
I know this cam is more aggressive than a stock grind. What are my chances of it even running with these components? I have been doing some online research and I'm more confused than ever. I'm starting to think that the naysayers are just concerned that I'm not even thinking about wringing every last drop of power out of it. Other stuff I've read says it would work but not be optimal. The truck is running a 700r4 and 3.45 rear gears with a 27.4 inch tire.
The engine is not in the truck and I'm getting skittish about going through the work of installing it only to find out I have built a dog.
Anyone care to school me?
