331 and 347 timeslips

Wondering what some of your et's are. Debating on whether or not to bother with an aftermarket 302 block. My goals are 12.0 and it must be super streetable and be able to run very long distances without overheating. Several people have said that would be easy with either motor. I have thought of doing a turbo build, but do not know if it's needed. Also do not know if I want to deal with the added heat, and trouble keeping it tuned. If it is needed its going to be hard to justify all the money along with the hassle of (rollerizing) an aftermarket block versus going to 351W. That was my original route, but already went through several roller 351 blocks and all sonic tested bad. Sorry to sound so scatter brained but please need some {experienced advice} By the way it will be efi and going in a 67 fastback.Have not decided on what tranny, but do have a 9 inch with 3:50 gear.

stroker question

Plan on 80% street and 20% track use. I plan on keeping my street tires on at the track if 315 or 335 would be enough to grip. I plan on having a/c and power steering. I have the opportunity to buy a 418 with sportsman block, hyd roller cam, injectors, fast efi, hogan intake, sheetmetal valve covers, and march pullies. This also comes with a Richmond 6 spd for 11K. The combo was on ebay a little while back and was on the cover of Mustang and Fast Fords last year. Anyway, this a little hard to decide on. I asked an engine builder how much I'll have in motor alone and he said around 6-7K and thats with a factory block. You add up painless harness,intakes, etc., tranny, and it really isn't too bad. But if I don't need a 351 stroker I simply do not need it. I would love to go with a 331 with AFR's and atleast bust off 12.5's, but I really want 12.0.

Thanks for the reply. Actually the combo I was looking at only had a 234/240 with 112 Ls. It was very streetable but probably has too much torch to hook up with, unless I did not use the 6 spd and went with an auto. I've got the dyno sheets, made max power of 450 and torque 466 at less than 5500 rpm. Anyway, thanks for the replies.
