J Heads

Well. Right now, its a daily driver, but I'm probably gonna get something a lil better on gas milage, but I'm gonna race it pretty much every weekend I can, also drive it to the track and back. For the street probably shift about 3-4 grand, but racing, just go all out, whatever it'll take. I'm not too sure about the bottom end part, what do you mean by that? Right now its a 71 340, j heads with normal stroke. It'll need to be bored, probably .030 over, then I'm probably getting KB243 pistons about 10:1 CR. Comp cams XE268H, MP race flywheel, street/strip pressure plate and clutch. Thats about it on parts, and I'll put different gears in it, its got 3.23s now I think. Maybe go with 3.91s. I'm also looking to get into mid 13s if not faster, faster is better, lol. Hope this info helps and thanks.
