Look in and also make a new post "Stage Block wanted" in the parts sections of both boards.
You can also try some of the big "racing" vendors like Cotton, Hartline , Anderson, Connelly, Duttweiller. Bare blocks are usually cheap. $1500-2000 it's the insides that cost alot ugh
550-600hp is the limit(mid 10's) and more your are on borrowed time in my opinion. But many have gone faster and still stay together. A stage block can handle double this and more if built right. Where do you live? So someone can suggest a builder nearer to you.
Running a forged crank in the stock block is a much better combo in my book. The cast cranks flex too much and rear main leaks results, even break with a block girdle. TA Performance now stocks forged cranks and others makes them, expensive but it's just money! A local guy broke his cast crank running on the dyno! (block girdle installed on the engine) Gene
Yea i will deffienetly girdle my block, and i will probally go with a forged crank. The stock girdled block is said to be able to take around 600 hp and thats all i will need to run high tens on race trim. I live in Gaithersburg MD. it's right outside washington D.C. Ive been talking to cal hartline of Hartline peformance and hes helping me set up my parts. Im gonna build the motor myself in my friends engine shop with a lot of their help. i just need to order the parts.
