Trick flow 240s on milder builds versus Edelbrock RPMs

Sage advice. If you already have the RPM heads......use them.
Simply for reference, on my bench with the only OOTB 240 heads I have tested, here are the airflow differences vs OOTB RPM.

Lift............240 additional cfm
.100..........+0
.200..........+0
.300..........+11
.400..........+37
.500..........+58
.600..........+65
.700..........+53

I do like the additional 240 airflow.

I totally would go with TFS 240 I tried both the Eddy's and TFS and really there is a day/night difference between them. On my 451 with a Perf rpm intake it made 612 hp and 625tq all while getting 12" vaccum. The best I managed with the Eddy was 550hp 575tq. Spend the extra few $$ and get the TFS
