Here’s the questions to ask yourself......
How much of a gain in power would you have to see out of the SFT to roller swap to justify the cost.......and does that seem realistic?
If it helps, here are the number 1 & 2 times for our combination:
11.52 120.28
11.58 117.98
Both were 511ci. I know for sure the second had a solid roller; pretty sure the first did also but, can't confirm.
The #1 motor made way more power than the #2 motor.
It just shows how important the overall set up is, as motors with very similar power to that one have gone well into 10’s in heavier cars.
There was def a fair amount of ET left in that car.
