My 70 nova build i need advice!

70 nova 350 turbo-350 pushing 300 hp.

I've decided to replace my motor...it only has about 400 miles on it..but i want to get to a mid-12 1/4 mile time which seems to require alot of power when in front of a 3-speed. i have full capability of rebuilding a motor and throwing a 700r4 behind a built small block or this carbureted LS2.

now...my question is...price wise and an eye on MPG whats the best way to go? the LS2 or a small block i build up?...to get mid 12"s?

the 2nd question... i have a turbo 350 auto on the column. i really want a TCI manual/automatic valve body transmission on the floor so i can race on the strip and control shift points or cruise around town in auto. is it difficult to retro fit? what all is involved? what transmissions should i look at? keep in mind i want at least a 4 speed.
Thanks for your time...

Being a big fan of the Gen III and IV small blocks, my shoice would br the LS2, and why not fuel injected? 400 hp out of the box with a pretty good amount of aftermarket stuff available for more if you want it. 20+ mpg with the 4L60E automatic. With 3.73 gears and a decent tire mid 12s should be no problem.

thanks...that never crossed my mind for some reason...probably what i'll end up doing.

If you decide to go the LS2 route, check out the Conversions and Hybrids forum here:

Lots of great info, FAQs and helpdul people. Was a major source of info for me on my LS1 project. I'll be happy to provide info also if you need it.
