dont the local autozone/advance store rent them???leave a dep and when you return the tool get your money back....
My opinion, but a big block is more pricy to rebuild than a small block and you could be into that if you try to cheap out. Dad had the machine shop do his 273 and it was $150, then they test fit the cam to make sure everything was good, and grooooovy it was! Either the right tool or machine shop.
