pat the list is longer than that just some are to shy to write their names down.

will it been a long summer racing some good some bad. just to update on what i have done. after trying to get the 1.70 int/1.44 ex head to work , which it did with a 11.48et@114mph and 1.54 60ft. but with 12psi of boost, 5psi more than with the 1.78in/1.47ex valve head. so last weekend i got the 1.80in/1.60ex valve head of the high comp engine and on to the blower block.i put a cut down size engbler valves in place of the ex valve, not trusting the way the ex valves looked after setting on the block in the back of the garage for 9yrs. will being a .080 over bore they looked like they would clear, should of checked, will after bending a pushrod on very first pass had to loadup and head home.spent the week tearing the engine appart. will all the intake valves cleared. the exhaust was another story,1 2 3 cyls all cleared, #5 bent the valve and the pushrod,4&6 had a shine spot at the top of the bore were the valve was just touching.will i pulled it all apart put the old 360cid valve back in the exhaust,put a notch at the top of all the bores so the was .030 clearence.put her all back together and headed back to the track for this pass weekend.now the good news, the boost drop to 10psi with the 1.80in/1.60ex head and et went to 11.42@117mph first run buy the end of saturday the car was running 11.28et@118mph.next morning the car was running mid to low 11.30et@117 to 119mph. so when i was out of compition rounds i switched the top pulley from a 36 tooth to a 34 tooth, the boost went back to 12psi but i ran a 11.15et@120.25mph fastest i have ever when,i just can bleive it.
