Heres some info for ya. If big blocks are the big dog on the block then how come in the NSCA and the NMCA, strictly race cars, the small blocks with turbos are the cars that have to weigh in the heaviest and have the most restrictions on them. They clearly make the most HP. again in certain applications if your planning on making over 2500hp then id go with a big block. But right now the big guns in those divisions like Pat musi and vinny budano run big blocks and if the turbo guys wernt restricted they would clean there clocks, and they have, thats why they restricted them. Not to long ago a guy with a twin turbo rob reager, beat up on musi and his 700 plus ci big block on 3 stages of nos with his 388ci TT set up that he ran all year long no maintanence, musi on the other hand went thru several motors trying to beat him. Then they changed the rules. Thats funny to take, a big block guy crying to limit the TT guys. Pathetic. One other interesting FACT, theres a big block in every trash truck made. Thats a good thing for that motor.J/K

On the plus side also, when your driving mello you can still get the 346 mpg.

Also, is your TT LS1 an actual LS1 block and heads or newer type?

I have looked at all the combos. N2O, turbo, blower. Some of the turbo SB do put out big power but big turbo setups cost more than a deceint BB motor and N20. Not to mention the fitment issues with a V-8 turbo. Hell maybe he should go with a V-6 Buick and turbo as cubic inches dont matter with turbos.

Racing-Following NMCA Extreme Street over the years....
This is what I have come up with... Mind you these are motors that ride the edge... and this is just my opinion....
Small blocks can run the numbers (ET wise), and even out run bbc's if set on kill with the weight they can run at... but they tend to break often... (burn up pistons)
Big Blocks don't need to be on all out kill, nor can they... The 10" tire, no wheelie bars, and weight they run at seems to keep it a level field.... They tend to run more MPH....
On a side note - Big Blocks tend to be hard on valve train....
Through my racing years I have found that Small blocks hate me... I have burnt up more than I can remember... I have run just as quick with them.... but I have also thrown a lot of burnt up blocks in the trash....
I am sure this is too much information and I am bored....

I voted small block because your engine compartment is pretty tight. If I were starting from scratch, I'd look at a big-inch LSx-based smallblock with nitrous. Like 440+ cubic inches. Check out the new GMPP LSx performance block for under $2000...

To the original poster, I would go big block. Obviously aluminum would be the preference, but even if I only had a cast iron one around, I would still drop the big block in there. Big blocks are becoming a rarer and rarer breed, and I think the coolness factor would be enough for me. Plus, there is that instant torque feeling that has been mentioned in this thread before. If it needs to be streetable, just don't go ape **** with the cam. Even a mildy built BB is going to make substantial power.
I voted big block as I have a complete 468ci ready to go into my project..in hindsight I wished I picked something to put it in that didnt weigh 4500lbs...but have always had an eye for the mid-80s trucks...good thing is since its a BBC with even the extra wieght I should be able to outrun 95% or more of whats out on the streets..its a 10.5-1c street motor.
Typically BBC stuff is going to be more expensive too...budget is always a driver.
Good Luck!
