rentahubby Posted October 24, 2016 Share Posted October 24, 2016 I'm at the beginning stages of my project 350 engine build, I'm confused as to what I should do. I have the block #3970010 and I'm taking it in to get cleaned and inspected. I'm not looking to turn it into a stroker but I would like 400-425 hp. Could this be done with this block? It's bone stock, never been bored etc. Where do I start after the cleaning and inspection? Could it be bored out? I have no clue where to go, its not something I want done right away due to budget restraints but I'd like to get a good build eventually. Any advice? I have an Edelbrock Performer intake already and a 650 Edelbrock carb, just need to figure out the right crank and cam etc. Quote Link to comment Share on other sites More sharing options...
72-CLASSIC_RIDE Posted October 24, 2016 Share Posted October 24, 2016 I'm no performance guy by any means but, to achieve that HP with a stock block and mild performance parts would require some Internal Engine considerations, Performance Heads, Cam, Carb, Crank etc. That HP won't come cheap. Sounds like you want a 383 CI Stroker Motor. Doug Quote Link to comment Share on other sites More sharing options...
dejh22 Posted October 24, 2016 Share Posted October 24, 2016 Depends on how much money you want to spend. Also if you will be running this at the drag strip? If you are looking for some get up and go power and a good street machine I have a combo I and friends have used for years. We take a 350 block like you have and bore it .030 over. Which now makes it a 355. All blocks have been two bolt mains. The intake you have is good as is the carb. I would use 64 cc heads ( camel hump heads cast # 461 or 462's) with flat top pistons. This combo will give you close to 10-1 compression. You will be able to use pump gas. I always use premium. The cam I use is a comp cam 268h. Plus I use a high vol. oil pump. To help the cause, some good rear end gears are helpful. I'm running a 355 gear. Like I said this is a good budget build. With lots of low end torque. I'm not sure what HP this combo produces, never had one on a dyno. My guess is some where north of 350 hp. Now if you are looking for something to really turn some HP, there are others on here that can help you more then I can! Dale 1 Quote Link to comment Share on other sites More sharing options...
dejh22 Posted October 24, 2016 Share Posted October 24, 2016 I forgot to say, I'm putting one together for my son. I had the block crank and rods. I bought the camel hump heads, cam, oil pump, Intake, carb, water pump, aluminum pulleys and brackets, after market stock type oil pan and timing chain cover, timing chain gears, overhaul gasket set, lifters, new stock rocker arms, push rods and other odds and ends. I do not have the total of the machine work yet. After all is said and done he will have a nice looking 355 with all new parts for about $2500. That could go north, depends on the machine work.

rentahubby Posted October 24, 2016 Author Share Posted October 24, 2016 Thanks Dale, that's about what I'm after, I have 373 gears. Non posi. That's a realistic amount of money for me. Could you message me with some particulars? Quote Link to comment Share on other sites More sharing options...
o_rod Posted October 26, 2016 Share Posted October 26, 2016 I'm just learning the ropes of SBC power but I have the same engine Dale mentioned and it does make solid power. I do find to get the benefits of the build you need to improve the valve springs and rev it out. I shift mine 5500-6000 during fun runs and it's a riot. Don't forget a good flowing exhaust! I think gears make all the difference. Seeing as you already have 373's you'll enjoy it even more! 1 Quote Link to comment Share on other sites More sharing options...
BigdaddyT Posted October 26, 2016 Share Posted October 26, 2016 My first engine build I used camel dump heads and made good power, I used an Edelbrock cam, lifters, and performer intake, that engine ran for a long time and was very reliable too. 1 Quote Link to comment Share on other sites More sharing options...
