Now a days I would build anywhere from a 565 to a 598, once you go over 600 comes with more maintenence. A good upper 500 inch motor would put 8.90 around 175 - 177mph which is upper side of the class speed. (this is based on a 1820 - 1900lb with driver 4 link car) Does this answer your question?

Ya, like you would know about Super Comp. :)

Chris knows, he won almost every race he attended, plus his dad is all world in Gas and Street.

I would also like to bracket race this combo too. We run 1/8th mile here. I want to run in the 5.0 range. I see these 4.70 and quicker cars overpowering the track too much.
Is there a combo out there that will be consistent running that slow on the stop??

Thanks
Chip

My 515 BBC (4.0" stroke 4.530" bore) runs 5.0_ in the heat at 136 and on the stop it runs 8.90s at 169 in a HT 1820# car and you can almost paint a dial on it.

If I was going to start over I would build a 540 and you will be able to bore it at least three times maybe four if it will go 4.625. I like to get as mutch out of a block as I can so the 565 option is out of my budget from the begining.
