The level 3 is still a good choice there but do as Steve and retard cam 4 degrees as dynamic compression gets too high.Ĭlick to expand.There's more to calculating the compression ratio than just the dish size on pistons. Make sure it's a small block rated convertor or you will give up an easy 500 rpm in convertor rating. Or even step up to the crower level 4 cam at 10 to 1.these cams prefer a 3000 convertor or better. If you go higher in compression you can do a TA 310 cam or the 413. 030 for about 50 cc chamber and about 10.05. 020 off heads for about a 53 cc chamber with net about 9.7. Expect no gains from the porting if you didn't smooth ports at valve opening.
Probably be best to leave it alone to keep velocity hi where you gasket ported head. You don't mention anything porting of intake to match gasket which is more of a bottle neck then the head port. Recurve distributer to have 32 total mechanical advance at 2600 rpm. The crower level 3 cam would probably give you best power degrees at 108(4 advanced) the TA 290 would be good after that or a custom grind from Scott Brown at. 045 gasket you can expect an actual static compression of 9.2. So assuming.060 down hole(no shaving of block) with the 10cc piston dish,58 cc head and. (Dish size,compression height, how far down hole the actually sit)Īccording to information I found the badger piston is equivalent to the 340p piston. Might even have made flow into port worse. Yes, porting to the gasket does very little without bowl work. To go faster 0-60 (8.2 sek) and on the 1/4 mile. With a quadrajet 750 or 800 cfmĪbsolute maximum for me, is a moderate idle.Īnd I will change converter to approx. # Cylinder heads ported, to match Intake gasket. Head Gasket: 0.040 cylinders 8 = 10.32 in compression ratio. Pistons Badger 525 compression ratio: 10.25:1īore: (diameter)3.80 / stroke:3.85 / Cylinder Head Volume:58 cc / Piston recessed 0.085 / Deck clerance 0.060?
I have a buick 350-2, SO 260HP in my Skylark 1970 I need some help in choosing, camshaft, lifters and valvesprings etc.
