There's plenty of small bore iron blocks 4.8/5.3 pushing na and boosted pushing 650-1000hp. I know a guy that just built a 5.3 LS with a 88mm turbo in a Mustang and it lasted only a couple passes. Ran a best of 7.07 in the 1/8. It threw a rod out of the block. There's a swedish guy that went 6.xx @ 202mph & a couple others with an LSX block too. Held together. plenty running 7's. All staying together. Go figure. Now that aftermarket needs to get on the ball with mopar blocks. Wouldn't mind paying for a 4.20 bore all aluminum LA block.
