Hello, fellas. I am in a quandary and I hope you can help me decide. I have a Camaro. Mild 350. Car is built solid the right way. Doing some major upgrades in the next couple of weeks. Here’s the deal: Swapping out 041 GM heads for Pro-Filer 185’s Changing cam from Comp Extreme Energy 262 to a retro roller 280/282 duration, .510/.492 lift, 108 lsa. Now the fun part. I bought a FIRST tpi unit about 8 years ago. Always liked the look of tpi but not the running out of power at 4800 rpm. The FIRST will make power up to 5800 rpm. A local Fuel Injection shop has said a FIRST with those heads will make around 430 hp and 500 tq at the crank. Strong. But, the FIRST is run by old tech as in a 32 year old GM ECM. It has a EBL Flash P4 installed so I can tune on the go and it self learns. I could go with the Edelbrock Pro Flo XT which is using the latest tech and software but will give up a little tq on the bottom for more HP at higher revs compared to the FIRST. Both of these systems will require a new fuel pump, lines, new gas pedal (mine is throttle rod type, not cable), VSS sensor, etc. I will need to learn tuning on both of them. Or I can keep everything in the car the same except put a more modern manifold (I have the original Performer from the 80’s) on and run my Speed Demon 650 or go with Sean Murphy Stage 2 Q-jet. Car is street driven and I live in Michigan so cooler temps can come into play. I would love the EFI but I know a well tuned carb will do the job. What would you guys do?
