Heard from a guy that they have released 454 Small Block versions.

Can anyone confirm??

 

yes

"They" have been building 500 inch SBCs for years.

All that has happened is, someone has now packaged it so you can just buy it, and you don't have to do it yourself. Kind of takes all the fun out of it.

It requires an aftermarket block with taller decks than stock SBC blocks, to accomodate the longer stroke.

 

They have a ton of power

 

Look at the TPI Board, TPIJeep?? has some dynos posted.

So, RB when you were building "fun" 500 inch SBC's, did you save the casting molds?

 

I've never built a 500, myself; but I know a few circle-track guys that have.

 

Well the part number for a SB 454 from Jegs is #955-101011. I guess if you had 10K just laying around it might be a fun sleeper engine, of course you would have some crazy 3rgener attempt to run a TPI on top of it then wonder why his stock 305 made as much power.

 

The truth is spoken. But we better be careful or else soon someone is going to step in and tell us that TPI is the best thing since butter on bread, we just dont know what we are talking about. I love hearing that. Especially from someone local, lets me know who I can beat down the 1320.

 

A search really would have got you all the information you required.

The threads over on the TPI board are linked below:-
