About to buy Dart 351w based stroker, Which one?

That's not as easy answer as it may seem. Again you'd be surprised what can be accomplished with the correct setup. Your induction will be the limiting factor. The 302 will have to work harder to make the same type of power but it can be done, it's not cheap though.

So you are saying that a correctly set up 351w based motor could make a given amount of power easier than a correctly set up 302 based motor? That's what I was trying to get at.

If a 302 would have to work harder, and he already has 351w stuff, then why would he be better off switching to a harder working 302 setup than a 351w that could more easily accomplish his goals? That's all I'm asking. That's how this whole thing got brought up. Well, other than the cheap shot at Mike, lol.

[351Coupe]

Yes it would be the easiest choice to stay with the windsor for sure. Same route I'd go. I think a few people just threw the 363 deal out there to be open minded to all options.

I can agree with that. I just thought that you were arguing that a 302 based block would always be superior. I think you mis-interpreted my cheap shot to foxbodymike, lol. I thought it was an easy shot, but I ended up defending my stance all night, lol!

Yes it could, but you did say it would easily outpower it. When in fact the 302 could make the power it just wouldnt be as easy. I never said he should switch to a 302 based motor, I was just defenending the fact that in the proper hands a 302 can make good power. The Original Poster should go with a 427-438 no questions about it.

So we agree about the end point. Why the hell were we arguing? lol!

Oh well, you obviously have more experience than me, so needless to say, I really like to see your input.

Better have more than a set of AFR's for that sucker

It has 454 CI. It doesn't matter.

put some afr 225's on it then put some Sc-1 heads and tell me 200hp difference doesnt matter

Lol, He was trying to be a smartass about what I said, but it backfired on him.

The difference is that we had an intelligent conversion, he's just talking shit.

I also never said that head selection didn't matter regarding ci. Obviously a .060 351w and a 427w will have different cylinder head needs to be properly set up. "Properly" being the key word, and I never indicated that ONLY ci mattered and nothing else as he would have anyone believe.

Actually, I have TFS 170's on my 363 now, I really think that it could use something a little better (AFR 205's maybe?), but I got these for next to nothing, brand new, still in the wrapper. A great improvement over stock D0OE heads that were on it.

Maybe because your swinging a 3" main crank instead of a 2.249" main crank, and that crank also happens to be 10lbs more of rotating mass. Or that your comparing a 4.060" bore to a 4.125" bore. I'm sure im forgetting some technical info so why don't you indulge me.

the 363's are badass, just prefer a larger cube 351w base. I would take a 363 if the deal was rite, but i would have to buy a few parts !

[badass88gt]

Torque?? Do you want to pull a trailer or race a car?? Your comparing your stock block windsor .060" over to a 302 based 363. First of all to even accomplish this with a 302 you need an aftermarket block. So with that you already have a stronger foundation than that of your stock block Windsor.

Yes an Aftermarket 351 based motor would be easier to accomplish the goals but that doesn't mean it's not possible to achieve with a 302 based motor. Your induction has alot to do with this as well. Build a 454 with some performer heads and I'll build a 363 with Highports and we'll see who makes more power. Enjoy your torque

can the 454 have the same highports?

just to be fair!

lol

[badass88gt]

what happened to your motor? Did you hurt the pistons with a bad nitrous tune up?

lmao, thanks jet. Yah i tried to cut a few corners, and learned my lesson. Did everything myself, and the 7al3 didn't pull the timing as it was supposed too. Burnt up a set of plugs. Manually pulled 8 degrees of timing, burnt up a 1/2 set of plugs. I think buy the time I asked for a little help, and got the car on the dyno, that the damage had been done. It's ok though. I learned alot over the whole process, and it really only cost me a set of pistons, and a few gaskets.

Car made good power, with a chunk of number 3 piston missing!

lol

[badass88gt]

Pulled the motor out, 1 bad piston.

Decided just to order another set of pistons, rings, bearings and headgaskets. Gonna put it back together, and try and get my nitrous no how up to par before i dump 7500.00 in a new setup.

thanks for all the help

well, i don't want that crazy stroke slinging around in there. i have heard the smaller bore, smaller stroke, 418-434 c.i. hold up a little better under the stress and load

Nothing crazy about this combo. A 4.125 bore x 4.10 stroke is a 438. With some big heads (320 cfm intake or larger) and the right solid roller camshaft will pull like a fucking freight train in every gear up to red line. A properly matched combo like this will get you well into the 9's all motor. If you have the balls to spray it, it can easily handle a 200 hp with the proper tune on it.
