I've got a 400 and a 350 block, one of which I am planning on rebuilding for my project and I was wondering with a TPI on top which would be best for low 13s?

P.S. Yeah I'm aware that the TPI can't breath enough for a 105 but it's all I have at the moment.

 

Uh, if you have the crank for the 400 then put that into the 350. A 383 will give you plenty of torque to compliment the TPI but will spin freely for days provided you pair it with the right cam and other stuff. If not, then build up the 400. I am assuming it is the SBC so it would be easy to find parts.

i 2nd that

 

Or you could just bore the 400 to a 406 and add the same parts that you would on the 383 and make more power! Bigger is always better!

 

Build the 400. choke it with TPI then regrow the money tree and get some better induction .

 

i would just sell the TPI setup with the intake runners injectors computer and ECM and with that money get a Carb intake and 750 holley pumper ot a sped demon. you could be ablt to get all that and maybe have some money left over for a cam (not sure how much the holley 750 pumper would cost but my holley 600 costed like $350)

 

The problem with this idea is I want fuel injection. I was just wondering if the tpi would support either engine into the low 13s in the 1/4.

That's what I was planning on doing :-)

this is true. i'm just a carb guy i always have been and always will be till they get rid of them.

i have heard good things about the holley super ram i'm not sure if thats the same thin as the mini ram..... anyone know?

Superram is different from mini ram. Superram is a modified version of the TPI setup, better runners and plenum. They flow pretty well from what I have seen and Lingenfelter has done some AWESOME things with superram setups on top. The mini ram is like a LT1 intake the way it is set up. It is a one piece casting and is rather expesive. They flow some crazy numbers and it is up to you if the nearly $1300 cost is worth it or not. TPI.com is the only place I have seen them sold.

Thanks for the info... can you put the mini ram on the L98?

 

If you want a mini ram setup, just go with the LT1 modified intake. That will be cheaper than a Mini-ram. And perform nearly the same. Or go with a Holley Stealth Ram.

Course, the stock computer is gonna FREAK if you change the combo its been tuned for without re-tuning the computer.

 

bill are you following me around?

 

well it will work on the 400 but in stock form will choke the hell out of it. they choked the stock 305s and 350s above what, 4500 RPM was it? I tihnk....anywho, with work im sure it would be possible, but with the money involved, some form of intake off of a newer set up would be ideal. I hope I am correct in what im saying.

cheers
