Engine boring

[anjieandjohn]

I am finally going to take the plunge and attempt a rebuild on my engine. I know that the 305 and 350 use basically the same block so my question would be how hard is it to bore out the 305 I currently have to a 350?

Thanks for the help

Need a 350 block.

They should be fairly cheap, IMO find a newer one out of a car, so you get all the roller lifter stuff and one piece rear main.

You can't bore it out that much . Max overbore is .060 .

You can , if you want to be different use a stroker kit and go .030 over to make a 334 .

He's also got a whole lot of wrong and questionable info there too. 305's suck compared to a 350, hands down, no matter how you look at it.

I know , and would prefer a bigger engine , and in fact have some now to build . I am doing a 60 over 350 for the 'velle , and a one piece 355 for the nicer Blazer .

But if a guy really wants to build a 305 , for either a claimer class , numbers matching 80's Camaro or Monte Carlo , or just to plain be different , 300 hp isn't out of the question

I am just looking at putting a fairly "fresh" motor in my truck for now...not doing any crawling just yet. As far as matching numbers, they will all match as the engine and drivetrain are the original from the factory. I know I will end up rebuilding the transfer case and tranny as well but I will approach those in a little while when I have done some more reading and all....Thanks for the help.
