My dad was finally able to get to test his combo with the new Trick Flow 190's today. I'm a bit disappointed in the performance, but I'm thinking there's something holding the car back, just have to figure out what. With some tuning hoping it'll pickup some.
Some specs on the car:
Car is a 1973 Duster - 3250ish race weight
Dana 60 4.56 gears
727 8" 5000 stall ATI convertor
Super stock springs
Doug 1 5/8" headers with a 18" collector into a 12" bullet muffler
750 Holley Carb
Lunati Flat Tappet .550/571 lift 256/268 dur
Engine:
360 bored .030 with scat 408 stroker kit. (5 cc flat top pistons)
Basically he just swapped the OOTB Edelbrocks for the OOTB Trick Flows with a few minor changes.
Edelbrock vs Trick Flow changes
273 rockers - Mancini 1.6 rockers - pushrods ended up being a little longer as well
Both engines used Victor 340 intakes that were OOTB, but it was a different intake on each motor.
Edelbrock - Trick Flow 190
1.497 - 60 ft - 1.505
4.454 - 330 ft- 4.452
7.012 - 1/8 et - 6.981
95.58 - 1/8 mph - 96.96
1000 ft - 9.193
1/4 et - 11.079
1/4 mph - 119.21
He ran the Edelbrock heads setup for a year. It was pretty much a high 7.0 car in the 1/8 in the summer and low 7.0 in good air. The run above was in Sept of the year. He never made a 1/4 mile pass with that setup. Only have 1 weekend thus far of testing the Trick Flows, so we will see how it preforms. He ended up getting in a gamblers race and the car went 6.98 5 times in the 1/8 so it's deadly consistent, I just thought he'd been in the 6.70s, or 6.80s atleast.
