No actually, its just not having a plan at the moment. I am not broke either, I am trying to do a 305 for once, seemingly how it will never run like a new LS3, or a coyote with any form of redeemable driveability. So I am shooting for mid 13's, to keep most imports at bay. Atleast, most honda/acura products. I graduated UTI, worked for Prewitt, then ProTech, then dyno operating at CCS, then (now) doing Top Fuel Hydro (#777 Disorderly Conduct) with family. I know cars, and performance, just NOT 305's with Vortec heads. From what I have gathered, the STOCK 081 castings are flowing 195/110. With headwork and a valve job its possible to make 240/155, which SHOULD be enough to take this 5 Liter GM in the 13's. Intake choice is going to be key, with a ported base thats siamesed, siamesed runners, and a port job on the plenum with throttle body, full exhaust and some 3.42 gears... I may have close to it. Add a stall and some trans work with a stick tire, and it MAY be there. Lets not forget the custom prom tuning... NOW... This IS simply nothing but a guesstimation.... I dont like gambling with a 305, or my money ON a 305... See how this can be irritating and warrant questions?
Silver, thats awesome! Pretty close to what i'm looking for...what do you guys think about the 1.94's in a 305?? Shrouded? Do you think some better valves with a nice seat job (4-5 angle) valve job in other words with some 1.84's would be better?? The cam is most likely a 206-216 .450 @112... something the TPI knows what to do with.. Maybe more but not much thats for sure.
