RE: 305 Build up... Experts needed!!!
With the price I was just trying to point out you can get into alot of cash in a hurry and why do that to a 305 when you can put less money in a 350 to make the same power the block cost is not a real big part of the equation. Costing it out: Balanced kit-$1100, bore and torque plate hone- $200, clearance- $150, clean cam bearings and freeze plug-$150, main bolts- $60, deck block- $150, heads- $1000, oil pump $65, oil pan $100, timing chain and cover $150, intake $140, rockers push rods $200, cam and lifters $200, head bolts and gaskets $150== $5340.00 damn I was off[8D]I could probably get it a little below $5000 with some vortecs and not decking but the carb will eat that up. Plus the assembly cost if you dont do it yourself aint no way I would put that kind of money in a 305 unless it was for some class racing..

I guess since you work in a machine shop that qualifies youto makethat kind of a stamement.
I know not of rebuilding 305s at all.
I only tried (emphasis on tried)to eek everybit of HP out of them I could since I DID rebuild them when we used to run claimer classes for IMCA Hobby Stock. They're a dime a dozen and not worth the effort unless in the case of the origianl poster and absolutely wants to keep the original 305 (why, I don't know since he says he wants more power)
If the main goal is power, then why would you even suggest stroking a 305? They have smaller bores which means more clearancing (i.e. more labor costs). The heads have tiny ports and valves, which will only get you so far. The intake ports have horrible short side radius compared to even a regular old 327/350 head. The list could go on. For you to make a blanket statement like the one above shows some shallowness on your part. Sounds to me like you must be repeating just what gets thrown around in your shop.
Oh by the way, I may not build too many engines anymore because of more important priorities, but I do get my hands dirty with one of the leading NHRA Stock/Superstock engine builders of the northwest. Try 748HP out of a little 314 SBC for a Comp Elim car. Over 2HP per C.I.all naturally aspirated. Like to like,a 350 will out torque, out HP, out Dyno that 334 and be more reliable simply for the fact that there were no block crank mods done. It'll probably get about the same MPG and cost A LOT less. GRIFF has way underestimated the stroked cost.
I think I'm qualified to make a statement about a 305.....................

Guys that claim 305 engines are junkare just speaking what they know not of.....or just repeating something they heard from the hangouts.

I owe you an apology. I may have come across a little on the caustic side and really did not intend to be that way. You have to admit that the average Chevy guy has always considered the 305 a boat anchor but, if built properly, they can make some good HP. I would always suggest a larger engine to start with but I read that he wanted to use his 305 and I wanted to put his mind at ease and to not get discouraged.
Again, I appreciate everyone's input and I did not mean to cut you down. I hope you accept my apology.

Hey MicroKid,
Did you swap do a swap from a TPI, I have looked into that and been reaserching. I feel I can to the swap I just wanna make sure I have step by step instructions.
