351w stroker/longer rods??
Ok, im kinda new to the stroker and the longer connecting rod performance tricks....i want to gain some power out of my 351w, i was thinking about a stroker setup, but i have also heard about using longer connecting rods on a stock stroke crank and you can recieve more power....can anyone tell me about the longer connecting rod setup and how it works, combos i can use for running on pumpgas(87 octane) or any ideas where i can go read up n learn on stroker setups and connecting rod combos?
and what are the pros/cons of stroking and longer connecting rod setups?

one more thing while i am thinking about it.....could decking and/or milling the heads or block help at all with either or of the above question that i asked for more hp and lbs/ft?

decking is done to ensure the pistons are parallel to the heads and yes milling will raise the compression. But don't rely on it as if the person doing the job doesn't have the ability or desire to do it right they may leave you in a position where your intake will not seal correctly anymore. There are many piston varieties out there so know your combustion chamber volume and gasket thickness as well as deck height and go from there.
As far as long rod check this out it gives a brief description

Anymore it is more realistic to just stroke it as a stroker scat crank runs around $300-350 you use your stock rods off the 351 and well any piston designed for a stock type 302 your choice of bore and compression will run $150+ and will work, so as you can see it is fairly inexpensive. Weather or not you can run on 87 octane will be determined by two things your compression ratio or the cam. Good luck, later

keep in mind, if you want to run on pump gas, dont get too crazy with milling heads, flat top pistons and stroker cranks and rods. these mods are designed to increase performance by raising compression ratio. if you raise the compression ratio too much, you will deal with detonation, pinging, hard starting, dieseling after shutting it off and the like. depending on what you are trying to do, a stroker 351w is a little out of line since a stock 351 with nice breathing heads and intake and headers will do pretty well for the street. back on the subject of raising the compression ratio, remember that you cant just raise the compression ratio and expect more power. rather, you have to build the entire package to work together. take it from me...i built a 351w with big valves, a nice cam and small combustion chambers. all it got me was an engine that hated running consistantly. after carefully matching the combo to the short block i already had, i have a very strong runner now.
