This is in my 52 Dodge 1/2 ton (link to build in my signature line). I have an Edelbrock Thunder Series 650 carb on my 354 Hemi. Timing is at around 11.5 degrees btdc. Using the MSD ready to run distributor I got from Hot Heads. Compression ratio is about 8.5:1. Running a Sig Erson cam. Trans is a TH350 auto. Even if I manually shift it...feels the same way. The truck starts up, idles and cruises fine. Doesn't smell rich or ping at all. When I really step on the gas, the truck just doesn't have the get up & go that I think it should have. It will accelerate...but it's kind of a slower increase in speed than I think I should have. It does this at any speed. So if I'm at idle and give it a stomp on the pedal...it moves forward. Doesn't put you back in your seat at all. Same thing if I put it in second while cruising at 35 and punch it. Just seems to be a little anemic in acceleration. If anyone is running a carb like this on their Hemi...what jets and rods should I be using? I'll have to look at mine to see what's in there now. Could my exhaust routing be stifling performance? Here's a picture of the exhaust routing now. I believe it's 2 1/2" pipe all the way around. The Driver side had to route around under the pan to the passenger side. The passenger exhaust T's in the pipe and then out to the back. There is a muffler after the merge too (probably 5-7 feet after the T) Anyone have any thoughts? I don't expect this to haul-ass. It weighs around 3500lbs without me in it...but I do expect a bit more oomph.
