347 Stroker

   First let me start with this...
I am not looking to make a monster HP drag strip killer. 
I am looking to have a decent dependable driver that has some cool/wow factors to it when it is done. 

I am now the owner of a 347 SCAT Stroker Kit with .030 over Keith Black pistons to go in my 72 302 block. Also going on the motor is an Offenhauser Dual Quad intake with twin 450cfm Carbs. Also have a timing GEAR SET that came with it all(not sure about that, but the cool/wow factor goes up with the noise and being able to say you have it) Already running the stock 1988 Mustang GT headers on the motor and will stay with them.

I need some info and advice. Again NOT looking for some 500hp beast!
What is the CC and valve sizes on the stock '72 302 heads?
Will the stock heads work decent with the stroker kit?
What cam should I use for an all around driver hot rod, IF it has a good hot rod idle and lope to it... WAY COOL!
Do I use the stock push rods?
Stock heads and springs... what ratio roller rockers or even exactly which ones should I use and why?

I think THAT will start the conversation!

	OH, I forgot! What will the compression ratio be with the stock heads and .030 over bored with KB pistons? What SHOULD it be to be able to run on pump gas with NO ISSUES! 9:1, 9.5:1, 10....you get the picture!

	Because you are using a 347 I would recommend using aftermaket heads. An entry level edelbrock performer head or better yet, something along the lines of a trickflow t/w will see substantial gains. I would probably run a decent sized hyd flat tappet cam with something along the lines of 230* at .050 and .550 total lift. 1.6 roller rockers. I would also consider dropping both the gear drive and go with a simple double roller chain as well as rethinking your choice on runnning dual carbs. I dont have the calculations for what your comp ratio would be, but I would shoot for a 10:1 (what size dish are the pistons) A simple 302 with a tiny cam and edelbrock performer heads ran 14's in my 4000 car. With a decent 347 you should see 13's running street tires and have good drivablitity.
