I believe the rear end is in good shape on my mustang. I have a lot of new parts on it to. New shock towers, shocks, ect. So the suspension is in pretty good shape. The FMXtranny is the only thing on the car I believe is like new. Haven't had 1 problem with it. Don't want to sound like a newb but I thought auto trannys didn't have clutches, also what is a "nutral drop". Please elabroate for me. Also can a windsor handle 4v heads, or is that just something exclusive to the cleveland?

 

Auto trannys dont, i believe you mis-interprited his statement.

Yes, a windsor can handle 4 v heads.

 

what kind of difference would 4v heads do for an engine?

 

It depends on how the engine is built. If you have too large of a port on an engine that isn't capable of moving the air the heads can, then velocity, and power, suffer as a result. When power suffers, the engine doesn't pump air as effectively and reduces flow, so you end up with large ports that will never see their flow potential because the engine can't support it, and may even lose power because of it. 4V Cleveland heads are generally not recommended for most street cars because the rpm range a street engine operates in usually isn't enough to move the volume of air necessary to generate effective port velocity(strokers being 1 exception). Port velocity is often going to account for more power production that flow rate. Remember that flow rate and velocity go hand in hand, higher velocity = higher flow rate, lower = lower. A large port CAN flow more, but only if the velocity is there to move the air. You're better off with slightly lower flowing heads that have higher velocity than you are with higher flowing heads with lower velocity, because remember that the flow rate is only POTENTIAL flow at a given amount of vacuum. Again, when looking it a head, velocity is just as important, or some would argue moreso, than flow

 

So a351w 427 stroker with 4v heads sounds pretty good then?

 

well, when you go with a windosr you really don't have to worry too much about the whole 4V heads. When Ford was making the Cleveland motors they cast two different heads. a 2V head with the smaller ports, and 4V heads with huge ports.

To the guy who said there is no such thing as too much, try putting a set of 210cc heads on a stock or mildly modified SBF and see how much power you don't make.

 

Yet again Hawkins a wrong response.Although not manual engaged adn disengaged clutches, autos have clutch just the same.look it up.And also when referring to 4 v heads you make it sound like 4 valves (2 intake and 2 exhaust) please tell me thats not what you mean if not i appologize. I say build the windsor as already stated since you have it. It will also be less expensive to build than equivalent cleveland. The cleveland is more often than not referred to as a "race" motor but ive driven both and theyre both fun to drive on tre road.Alot of a motors driveability has to do with driver skill also.Well good luck and have fun.

 

If you mean 4v cleveland heads, then you first need to find a very $pecial intake to allow C heads on a W block. Depending on your cam, they may work well but there are many head choices available now.

 

Everything in perspective. You wouldn't put a set of ported heads on an stock engine anymore than you would put a 700dp on a stock 302. The guy was talking about building a street motor.A properly built 4V cleveland is not lacking for low end torque. Period. Improperly put together, sure.

 

Pretty much any aftermarket Windsor family head is better than any stock Cleveland head. Stock for stock, Cleveland heads are better, Windsor family stock heads have ports so small you can get a finger stuck in them. [>:]If you're gonna go to the trouble of putting C heads on a W, you might as well just get some good W heads like AFRs or Darts etc. There are a few good aftermarket Cleveland heads as well, and they generally perform very well. Clevors can work well if done right, but if you honestly have to ask questions about what needs to be done, don't do a Clevor, you'd be better off building a more vanilla W with some good heads, you'll most likely make more power since it's harder to get wrong than a Clevor is.

And yeah, there is such a thing as too big. That's why the Boss 302's sucked on the street, they had ports so large they couldn't make muchpower under 5,000rpm. Ran fine at 7,000rpm though
