I am at the point where I need to give the go ahead on building a long rod 306 or a 347 stroker shortblock for my 65 Comet. I have provided the std bore flat tappet 302 block. I have been quoted a $300.00 difference between the two with my choice of custom grind that Bullet Custom cams will cut. They will make a cam grind recommendation based on my modifications, but I was hoping someone may have a good proven flat tappet hydraulic cam for a weekend drag strip/ street car. Is there much of a difference in HP between the durable 306 and a built 347?
I turned 13.80s with a basically stock 302 block and heads, but would like to see some high 11s low 12s on motor.
Help me make a decision and cam selection please. Don't want to turn more than 6200 rpm if possible.
I have ported TFS twisted wedge heads
1.6 roller rockers
2800 Pro egde stall
3.55 Trac Loc with 23 inch tall drag radials
Hooker super comp headers
Edlebrock Air gap (port matched #1250)
Holley 650 DP
track is at "0" elevation and Hooks almost all the time.
*** I had to reword that whole thing.LOL. I couldn't even figure out what I was asking. I was very tired when I wrote that. Sorry. It should be better now.
