Re: motor size
I would recommend that you put the ZL1 block away for another project and build something with an aftermarket aluminum block. For the money it is hard to beat the value of a 540,572 or 632, when they are built right they will last forever. You do not have spin them more than 6000 rpm to make power and there is a bunch of torque available from the moment you hit the throttle.

Re: motor size
I agree with Mark. Here is a video of my 540 dart block and dart head set up. 725 horse and runs on pump gas. And will run 10's all day possible 9's with a day of tunning at track. Plus I can drive it anywhere. But the 454 stroker would be cool also. Good luck.

Mark Sheppard [/ QUOTE ] Mark, you are probably right..but I already have the block..and another block is not in the budget..but 540 inches...Hmmmmmm thats sounds cool, but 480+ inches aint bad either
