Default Chevy 350 Build Question.

okay first off I am new to engine building.

I have a gen I sbc 350 4 bolt main. I want to rebuild this thing for my CJ7 jeep. I want somewhere between 325-350 hp. I would still like to run easily on 87 octane.


What kind of engine kits do you guys suggest? Also I need some new heads, cam all that good stuff. Mine old ones are kinda beat and its prob cheaper to buy new ones then rebuild. I have a edelbrock preformer 650 cfm carb. Will this be enough?

Anything I have missed please feel free to add.

Thanks

Brian

Doesnt take much to get 1 HP per cubic inch, a small cam and some stock port vortec heads will get you that power and even more torque. 218/220 duration at .050 and 470ish lift can do it, flat tops or dish pistons will work and the carb you have will be fine.

one thing to keep in mind about the double hump heads is the lack of accessory mounting holes drilled and tapped in the front and rear of the heads, this will limit you options for mounting accessories, you'll have to go with a short water pump etc etc

not that its a bad thing but just keep it in mind if you have a budget and already of parts

The seller of the heads just emailed me and said they do have accessory holes. And 64 cc combustion chambers
