E5TE heads - They have less then 5k miles, new valve job, teflon valve seals, milled .030. are these any good. suposidly these are just like E7TE which came on 87-93 mustangs. If they are better than stock i plan on getting them, because the price is a steal.
All I know is my uncle's '89 Mustang and the '93 motor my dad had in his '84 GT both used to run pretty good.
I think E7's are better in stock from than the E5 ... however, since they have been rebuilt all bets are off ... they could be better than a stock E7 depending what was done to them ...
But would they help me breath better at high RPMs. I realy need some heads and i dont wanna spend and arm and a leg.
You would need to find out what size valves were put in ... if they are just standard size valves then I would think they wouldn't breath any better ...
You said the heads were milled .030. That puts the combustion chamber closer to the pistons and raises the compression ratio. When you say an engine is bored .030, that means each cylinder was made .030 bigger in diameter. On a 302, that's another 4 cubic inches making it a 306. You will spend a lot of money to get E5 heads to breath the best at high rpm's. Look for a set of used aftermarket performance heads.
spinning a motor way upstairs does not mean more horsepower. You need to determine were your power range is and thats were you want to keep it. If you car makes max power at 4,300rpm.....why would you spin it to 6,000 or whatever. You can take a mild build 302......and make good power at the 4,500 to 5,000 rpm range. To reach maximum reward for a head change, you need to make sure your intake, cam and exhaust are at the same level performance...just putting decent heads on a stock 302 is not going to see full potential unless other areas are addressed as well.
Ok. What i have is a mild cam, stock intake and glasspacks, i am looking for a 4bbl that is cheaply priced so i can rebuild it. All i really want right now is to get some more power, on a not alot of money. I mean if they are better than stock i would consider getting them, but if sombody here has better heads for cheap i would get those.
you can do a compression check or leak down to see if the rings are ok. no sense in investing money if the block is worned out. refresh the bottom end, and then install the cylinder heads !! they flow better and you will get better gas milelage with free flow mufflers 2.5" exaust pipes, ECM Duraspark ignition, and a 268 degree cam. you can do it one modification at a time or as the money tree permits
Exactly. It's a package deal to achieve total combustion harmony:bananaman You can do it one part at a time as budget permits if you are the impatient type. However building the motor the way you want it the first time makes more sense. Then again who cares as long as you are enjoying you maverick that is all that should ever matter!!!!!!
There is a reason those heads are cheap, and it isn't because the seller likes you. It is really hard to make good horsepower cheap. Most people who try and up spending more in the long run.
you can also collect the parts and then do it up nicely !! thats what I did !! did it once and the right way !! it runs strong, economical, reliable
I dont really know what you mean by refresh the bottom end, most 302 are top end, I already have the engine rebuilt with a mild cam, i am looking at a MSD ingnition, and a new exhaust. But money is a little tight for me.
