Here is what I have now:
I have a 9.8:1 383 sb. currently it has a Lunati 230@50 .480 lift hydraulic in it. The cam is not a small base circle cam.
A performer RPM Holley 750 vac secondary with a HEI that has been worked to do well with the current combo. The motor only has about 4K miles on it but its been in the car for about 4 years.
The car has a 700r4 in it with a 2800 stall, 4:10 gears, Southside machine uppers and lowers and air bags in the rear. Three way comp eng rear shocks.
When I built the motor I went a little conservative on the cam because it was my daily driver at the time. Now its going to be my weekend toy, and will go to the track once in a while for fun.
The motor is out of the car now because I am getting the car painted. Finally doing it right, media blasting it new panels the whole nine yards. That’s another story.
So this is the time if I am ever going to change the cam.
Okay all that being said here is my question... Would it be worth it for me to put a bigger (not huge just bigger) hydraulic roller in it? Horse power wise and to allow the car to run 12"s with out much trouble. And if so what would be recommended? Another reason I didn't go any bigger was because it was not a small base circle cam I was having probs with the cam lobes hitting the rods... if I remember correctly. If I do go with a roller I am assuming I will need a small base circle cam this time if I go bigger???
I hope I covered everything
Any info is appreciated,
Greg
