I just put a new Harwood fiberglass cowl induction hood on the truck. No more rusty hood with sawz-alled hole in the middle.

Racing Information
My 78 chevy truck has a 400 ci. small-block bored .030 which increases it's displacement to 406 ci. The blower is a Weiand 177inch Pro Street with a single 750 Holley calibrated for the blower or a 780 cfm Quadrajet, depending on my mood. It has 5.7(350 H-beam 4340 forged steel Eagle ESP connecting rods with 190,000 psi rod bolts) instead of the stock 5.5 inch 400 connecting rods. I had 190,000 psi studs installed in the crank's main journals (instead of just bolts, since superchargers stress the lower half of an engine significantly). The pistons are Keith Black dished "blower pistons" and are bushed(use circlips as extra reassurance to hold the wrist pins inside the pistons). The cam is a custom "blower" grind that I had Isky Cams in Cali. cut and is based on a "small base circle"(lobes are smaller in diameter and I use longer push rods) because the 400 has so much stroke that the H-beam connecting rods were going to strike the camshaft. The cylinder heads are Edelbrock Performer RPM's with 2.02 intake/1.60 exhaust and are CNC ported and polished. They are bolted to the engine using 170,000 psi Trick Flow head bolts and SCE copper head gaskets(used to eliminate the common problem of superchargers blowing head gaskets. The pushrods are .084 thick Trick Flow's vice the stock .040 thick ones and I use billet aluminum 1.5 roller rocker arms. The exhaust consist of 1 3/4 Hedmann headers flowing into 3 inch "true duals" utilizing an "H-pipe" and ending into Dynomax Race Magnum Boxed mufflers which flow straight through instead of restrictive chambers. The transmission is a TurboHydromatic 350 with a B&M shift kit, B&M super cooler, shifted by a B&M truck megashifter and power is then sent to a 3.73 detroit locker 10 bolt rear end. I have had excellent results with the GM 10 bolt rear ends(ElCamino SS454 had 10 bolt also) and see no need to add more weight with a 12 bolt or custom ford 9 inch). My next working project is building a TH700R4 overdrive transmission with extreme duty input shaft/drum and "sunshell" to handle the torque of the supercharged 400.

Stats
The compression at idle is 8.28:1 and rises proportionately under boost. I use 2 different pulley combinations depending if I'm aiming for 20mpg on highway or a performance set. (yes, supercharger cam profiles enable the builder to stay relatively mild for a nice blend of performance/economy and lower compression helps lower temperatures at idle). The stock pulley pushes 8 Lbs of boost and my hi-po pulley pushes 11 pounds of boost.
