Update........A couple of things........Took the car to Nickey Chicago for tuning......during the tuning process a couple of issues popped up.........#1....I put a Concept 1 front drive set-up on the car to allow for the A/C compressor to be mounted up top ( no room in the stock low position due to cross member clearance issues)....this setup drives everything off of one 8 rib belt.........and in the Dyno tuning process when given full throttle, the belt squeal made it apparent the Belt wrap on the crank pulley was not the best along with the belt dust all over the engine..........I had a Gatorback belt on the car which has cross grooves which make the belt quieter,........But the guys at Nickey told me to get a Gates Fleet Runner Belt which doesn't have the cross grooves and will give more gripping surface..........Only made 7lbs of boost with the slippage.........New Belt installed..........2nd.......the Horsepower on the Dyno was lower than I expected..(442 RWHP).....Also in driving the car home it ran good but just didn't have the power of the LSA powered 66 Chevelle) ............After getting the car home I put it up on the lift and after looking at the exhaust system..........I now realized that I should have not used the stock cast iron manifolds........and when the exhaust was fabricated, the 90 degree bend put in the pipe coming down from the manifolds actually reduced the pipe diameter quite a bit..........so....as I looked at this set-up, I really realized the Choke point of trying to push all the exhaust at RPM thru that area of pipe........So..........Here we go again......LOL......Ordered a set of 4 tube headers........(pic's to follow).........It will be interesting to see what the numbers will be after getting everything installed and tuned again............I'm also going to install a set of Ring Bros Hood Hinges........
