I haven't posted on here in a while, but I have a few questions. I have recently gotten rid of my camaro and have picked up an '86 c10. It has a 350 small block and th-350c trans.(lockup convertor and transgo shift kit) I was told the block came out of a 69 corvette. I am looking to build the motor to 400hp+. So here are my questions.

How can I verify that the block is indeed from a 69 vette? And if it is, is it a good block to start with? Motor does run very well, and it does have a Summit Racing 1103 cam and lifter set in it. Seems to move out decently. It is a 4-bolt main block as I have checked that out. Carb looks to be an Edelbrock Q-jet. Not sure on cfm, but I was looking at the Holley 670 street avenger as a replacement. Intake is an Edelbrock performer. Distributor is some old HEI.

What are your opinions on the lockup convertor type th-350's?

Also it has the factory 2.43 gears and a lame peg legged rear. What would be a good rear set up?

Are the numbers I'm looking for reasonable? And if so what would be a good Head/Cam combo? Anything over and beyond 400 horses would make me happy. I do not have a budget at this time but I guess I would like to keep it under $2k if at all possible. The truck will see track time in the future. Streetablity is NOT a concern.

 

get the vin number off the back of the block and find a vin decoder on google. you can find out what motor it is that way. 3.73 gears would be a good gear to start at if you decide to still drive it around and you can sometimes find a set in a junk yard cheap. vortex heads are good to run they flow well and are easy to find and not over priced. you could probley talk to a few guys on here and get a good cam spec to run.

i am building a 84c10 with a 99 roller 454 im leaving the motor stock and gonna run a s400 borg warner single turbo on it and see how i like it. good luck with the build
