hpe600rt, .Pete,my engine builder says with what all we put in it we could be looking at somewhere in the neighborhood of 375 H.P.Not bad for a little 273.it is by no means up to passing muster in the F/S class anymore but when the G.C.'s raced it believe me they did PLENTY of things that got extra H.P. but SOMEHOW pased tech.inspections (most of the time)and they only match raced against other Factory teams.I plan on the same type of match races and will only have to pass a safety inspection not a technical inspection (already checked that with the NHRA inspectors)so I took some liberties. Here's a really good one for you. I had Pete put 318 valves in the 273 heads which are 10 thousandsths bigger in diameter intake and exhaust.By the way ALL of the valve train is Titanium from Mopar performance.Then Pete cc'd the heads to exactly what the G.C.'s had achieved 57.3cc.The cam is a Mopar Direct Connection double roller rocker with .557 lift with 296 duration with an overlap of 76 and a centerline of 110.The Rockers are blue aluminum and have a 1.50 to 1 ratio.Comp. ratio is 11.2 to 1 w/JE custom made domed pistons.Dual plane Hi-Rise intake,windage trays upper and lower.Mopar perfomance distributer.Holley 650 Dbl.pumper.Bored .40 over.10 qt.oil pan is made to G.C. specs with high pressure,high volume oil pump w/hemi swivel pick-up.Mopar performance race fluid vibration damper,11" clutch,and the whole thing was balanced and blueprinted.Crank is stock billet steel.
