The engine build information:
Engine block- truck roller with 2 bolt mains;
Cylinder heads- PBM performance products, alu heads with 2.02 intake, 1.6 exhaust valves, 200 CC intake runners ( not sure what min. Cross section area is -better measure of head performance) their generic heads.
Pistons- flat top w/ valve reliefs, hypereatectic coated ( see pics above).
Rings- PBM moly ring set.
Cam- Erson - HR Energy Plus Hyd Roller ERSE119840, duration @ .050 218I/226E, .480 lift w/1.5 rocker, 108 lobe center (lobe center and duration/overlap very important to how engine performs)
Hi-tech stainless roller rockers( these are over kill, just had them)
Push rods a little thicker/stronger then stock, to minimize flexing.
MSD Distributor, 34 degrees total advance, all in at 2000 RPMs.
8 MM spark plug wires.
Edelbrock Performer RPM Air Gap intake manifold.
Stock oil pump.
Stock rods and crankshaft.
Carb- Quick Fuel Hot Rod series with a few mods made by local carb specialist.
A few specifications:
CR is 9.8
Quench (piston to head clearance) .055" ( important allows higher compression wo/detonation)
The above is a general summary. Will post dyno results next.
