well its been a while since i have been on here ... i just got some money saved up ... my build has not progressed at all except the strip her down part

i need to find a good block capable of supporting over 500 without splitting down the lifter valley looking to stay in the small block range 289 302 327 347 ect ... maybe even 306 ... the plan is to throw a Garrett tv7705 on it with all the bells and whistles .. lol
ive got the money to do the build but i need a foundation anyone got a block from the 60s or early 70s i have heard good things about them being up for the task at hand i just dont have enough money to go get a sportsman block or dart ect..... lemme know

thanks -Eric
