I have inconnel exhaust valves with oval port heads, the bottom end is stock. There is a blower cam in there but not sure what one. Are the gm rods strong enough for 700hp? If I change the pistons will it last.

I appreciate the input from everybody 5lbs it is. I run 93 octane, it is avaible on every other corner. I wasnt sure to rebuild a perfect running engine for 2 extra ilbs of boost or leave it alone and spend money elsewere

93 is NOT available on the West Coast. You go from 91 to race gas out here. Its not an issue of paying for good fuel, its an issue of availability. UD . |
No 93 octane around here either anymore. We had Amoco Ulimate at 92 octane until last Spring, but now even that is 91 too.

I agree with what Smitty said in post #7 except when I had my whippled 502 I had the heads ring cut for the Fel Pro Loc Wire head gaskets. 6 lb boost, 8.75 pistons, 93 octane.

Yea, what's up with that Dave? Is it because our politicians are environmental communists? :mad:
. Im not sure what the deal is. Its likely more market factor than anything else. Performance Autos are are being mfgr'd to tolerate 91, and its cheaper for the oil companies to produce. UD |
