that's just dumb

 

whats dumb

 

guess

 

what that im trying to kill the engine, im not really tring to do that i was being sarcastic.

 

If its still fine go to a 306 with some ARP Wav Loc Rod bolts keep the stock crank and rods get some forged pistons, get the block fully machined, then bolt it all back together for a cheap rebuild ... if you want more power spend the cash and stroke it...

 

i was thinking of making it a 347, do you have to do heads after that.

 

No but if you keep the stock heads you wont make much HP unless there are severly ported and decked......it all comes down to how much hp you want....and how much you want to spend... you can go on EBAY and pick up a cheap stroker kit with a new crank rods and pistons..... but if you keep the stock heads then you are shooting yourself in the foot.... I would get a stroker kit off ebay, but the trick flow package for 2 g and with the 347 and that package you are making deadly N/A HP plus it comes with everything you need top to bottum

 

how much hp do you think it would lay down?

 

With what setup?
