If money was not an problem go for this 600hp 370 from a 302 dart block.

But to use a stock block go with a 347 with blower we just had one on the dyno putting out 573hp.

fanx for the advs my frend!n i rely like thi forum peple r relly nice and helpful1!!!!!!!!!!!!!!`

 

first off half the 4.6's made were at the same plant the 5.0 was made in windsor canada, second of all the stock rotating assembly is good as long as the block is the internals are forged, third u wont even come close to 500 hp with even a good h/c/i swap
go with a 351w or cleve, they can hold up to 850 hp with forged internals and u dont need as much to get there after that plus u could find a 351 in a junk yard for like 300-400 dollars rebuild kit is like 600 then the h/c/i would cost about 2500 and then go with f/i

 

most of your power will come from your heads so thats where i would start unless you are looking for torque then you want a stroker kit but not too big

 

If I start with a stroker kit, what would be the biggest one I'd want to use with the stock heads or say with the cleve heads?

 

347 from a 302
408 from a 351w

longer stroke = more torque = slower revving = usually lower redline
shorter stroke = less torque = quicker revving = usually higher redline possible

this has been proven time after time with local roundy round track motors. our fav for SBC stuff was a 400 block with a 327 crank - it equaled out to just a touch over 350 c.i. which made it class legal and you can hold the throttle down longer before going into a turn, and they spin back up quicker coming out of the turn.

how big of a stroke you want is all in what you want it to do with the motor. honestly although i have a 302, i would rather have a 289 crank cause the little loss in torque would be made up in the quick snappy rev's which is great for street driving. if i had a 4x4 pickup and wanted to climb hills i would want a low revving motor with a huge stroke for that grunt off the line.

 

Here is the baddest 2007 naturally asperated 302.

Pushing 400 HP and 390 FT LBS Torque

 

something feels dirty about that motor being a 302 even if it is a 302. couldnt they have made it a 301 or a 303 =)
