Well, my boss is looking for a fun street car with full spool in the 2600-2800rpm range. He only plans to run 8-10psi intercooled in his 67 camaro. The T74 was the smallest I recommended for spool time. We were looking or a T76, but found a great deal on the T74. He just got his flow #'s for his Dart Pro 1 heads he is going to use on the 383. Lloyd Elliott ported them BTW...

237 cc intake port
74 cc chambers

Flow #'s are . . . . .

.2......142/105
.3......199/145
.4......248/175
.5......281/202
.6......302/217
.650...314/226
.7......317/229

2.08/1.625 Ferrea 6000 series valves
Comp 26120 big bee hive springs
Titanium retainers
10 degree locks
spring locators


Once again, Lloyd does great work at a great price...

 

Lloyd definatly rocks!

 

not bad. the 500 lift numbers are about what hes getting top end on lt1 castings

 

Yeah, if you compare the LT1 stuff at ~.600 versus this, he is 20fcm higher on the intake and 30cfm higher on the exhaust. Not bad for the same price of porting, just a different head to start with

 

Yup, do you know what the heads flowed stock?

 

The Pro 1's were castings, unported.
