I am hoping to give it a try. I posted about heads in another post and I am really looking for a high 9 second pass. I always run pump gas on my stuff. Flat top 4.10 bore 4" crank. I had open Eddie heads before but now going with the Indy 360-1s and some porting. Roller 6.56 cam and a 950 HP carb.. Oh yea a 8.75 rear end " LOL
