375 to 450 rwhp will be tough on a 3k budget....you want a well built 347 short block.....www.fordstrokers.com.... add a set of decent heads like afr 185's or trick flow 190 as cast heads and a decent intake and tune and all supporting mods and 380 rwhp will be a reality oh and 375 to 450 won't happen on a h/c/i 302 without a power adder

^^^^^^^that question can have a range of answers, now take this statement for what it is, cause there will always be exceptions to the rule.......most average budget h/c/i 302's using the factory ford rotating assembley end up producing anywhere from 280 rwhp to 310 rwhp and the upper limit being with a dyno tune/ chip....this is the average......like I said were talking just bolt it on and go deal.....there are tons of tricks that can be done to up the level of hp but mods cost money.....I've never dynoed my builds as I have gauged them in terms of et's and my last h/c/i 302 in my 85 was a dome piston short block and the h/c/i on it was 11 to 1 compression and it ran 12.20's @112 so rwhp if I had to guess was most likely around 320 to 330

i have seen 306's in the 9's with around 600 hp , but those were strait race cars

and for that power and budget the only way would be a rebuilt shortblock,decent alum. heads,trickflow intake, and a decent cam and a good 100-150 shot and can all be had for 3 thousand on good budget shopping.

rebuild the block and through a supercharger on it, you'll be close to 350-375

with a 160k on the bottom end I'd pull it and rebuild it and bore it .030.....but by the time you do all that you could probably buy a 306 ready to go for 1200 to 1400......a well built 306 with tfs fast as cast 170 cc or 190cc and custom cam will yield you a power producing combo, yeah it'll cost a tad more but what's worse..spending twice as much later on to redo a disappointing combo???.....afr 165's or 185's will work...when I used 185's on my 306 I had dome pistons and it worked well and I threw a 100 shot on top of that and ran 11.34 @ 120..........so if you plan to throw juice to your 306 combo then 400 will be possible with a 100 shot
