g'day
i have finally decided to do abit with my 71 f100, i've gone and got me a 460 and c6 and now i want to stroke it!! at the moment im after a 557ci kit, and some edelbrock heads. has any one heard any stories about this type of combo.... or if it even a good idea, because i kinda wanna keep it sorta realiable. has anyone got any tried and tested combos that they can give a good wrap, i don't really want to fork out big wads of the folding stuff for s*#t if ya know what i mean.
cheers

Hey getuted,
Sorry I don't know of any stories on that type of combo. Where abouts are you?
Sounds like one tuff project there!

I have heard of a 600 stroker kit. Back when i had my 429 I was enquiring with COME engines.

Maybe they could help you now. However I'm sure I've seen earlier threads on this before. Do a search.

The 557 kit may surprise you when you build it because the 4.5 stroke crank pulls the piston out of the bottom of the bore so far that you can see the piston pins. This has not proven to be an issue or cause failure, though. Never-the-less, for this reason I opt for the 4.3 stroke 533. This option also has a better rod ratio resulting in less side-thrusting of the cylinder walls.

The 557 with Edelbrock heads is a good combo and has lived on a street engine I know of for a long time. Strengthening of the block is a must, with a main stud and girdle kit as minimum and 4-bolt modification even better. Block fill to the the waterpump holes is also helpful in supporting the cylinder walls, but beware that reduced cooling capacity will be cause for your oil to absorb more heat, so get an oil cooler to make up for it. A block set up this way should be good to 900 HP capability. Keep the motor in excellent tune to reduce the possibility of cap-walk.

I am of the opinion that if you have a standard bore block, build the 4.5 stroker to a .030" overbore 545 cubic inch engine, and save yourself the future overbores for long-tem use of the block. (A 4.3 stroke 533 would be a 521 at .030 overbore.) This also provides stroger cylinder walls, especially in an engine that has not been block filled.

VPW do stroker kits.... The 545 and the 520 are $5000, the 502 is $4000.

If you want cheap and reliable go for a 520 with a scat cast steel crank. Don't fill the block for street use and keep the rpm down. Edelbrock, Trick Flow and Ford all make good aftermarket aluminium street heads. Which is better? Who knows. To keep costs down find one that comes fully assembled and uses standard intake and exhaust locations.

600 cubes requires aftermarket (expensive) block. 4.6" bore plus 4.5" stroke = 598 cubes.

as good as that 600 stroker sounds( believe me it sounds good) i've gone with the 557 stroker from scat, also with the edelbrock 60669 heads, talked to a bloke who actually has one and he has had no issues (touch wood) but he is 5000rpm limited, but it still turns the tyres in EVERY gear. trying to get a cam package now, little help.......

RevHeadRon

but big blocks are good like that you dont' need to use 8000 rpm to make power, plus you have all those ponies just off idle, right where you want them
