Hey guys, I have a pro street 73 camaro, and i just took out a blown 350, I want to go big block. This is going to be a street car only, dont plan on racing it, just want a good running fast street car. I want to be able to run the blower in the summer months, and run without it in the winter, question is, should i go with the early motors, or step up to the vortec., I have a line on a 7.4vortec ( i think its a l29 ) out of a 99 surburben, its completely stock, I like the new roller cam idea, and will the motor be o.k. with the 671 on top. or will i need to do alot of changes. hit me with some thoughts. thanks Tony
