All things being equal, you will ALWAYS make more power with aluminum heads. The compression loss from the aluminum heads would have to significant to see a power drop off. Never mind the 50+ lb advantage the aluminum heads give.
All things being equal, you will ALWAYS make more power with aluminum heads. The compression loss from the aluminum heads would have to significant to see a power drop off. Never mind the 50+ lb advantage the aluminum heads give.? I feel like I'm giving up a lot of power as I'm losing compression with the aluminum heads.
Thanks for all the help.
Ah bin lurnin.....That is true, you were not specific:
' a '97 didn't come with the 5.0l'
You have a 97 mustang with a push rod 5.0? Cool
You are correct sir!
Thank you . He could prob mill 3-4cc out of the chamber and be aheadAll things being equal, you will ALWAYS make more power with aluminum heads. The compression loss from the aluminum heads would have to significant to see a power drop off. Never mind the 50+ lb advantage the aluminum heads give.
You aren't the only one that has bought those heads or others like them, you just may be the first around here to admit you bought them and they were crap.Yep, I'm embarassed to admit it, but I tried a set of Speedmasters. They took soooo much work to get decent numbers out of them... I could have bought a good set of heads for less money than I had to invest into them. Not to mention the pending sense of doom you feel on every pass crossing your fingers that they don't fail.
And another thing, I don't plan to stay in budget, and I'll never sell the car. Unless I could go directly and buy a better foxbody.Sorry I didn't get back to you guys for awhile. I guess I need to look for better heads. I got a good deal these heads. So I'm not out much. So does anyone have a set of heads for sale??? I have a 351w block. But it needs everything as I cleaned it using electrologists. But I can do it all in house. Just need to get past Xmas

I'm gonna do a compression check this week and I'll report the numbers. I hate to say it's a bent valve as it runs good. I really am leaning more on the intake being restriction. I see there cheap heads, I wish I got better ones. But I'm gonna keep my eyes open for a deal on a better set.
Either way I go on the build turbo or n/a, it will be ready for the spring. But I do agree with spending the money on 351w. It's just turbo is cheaper I need all new bearings and freeze plugs before I even start with the cool parts.
So I did the compression check. I did do the motor cold. And I did the fuel pump off and work. All cylinders ranged from 110-130. I had the also tested the valve springs. Coil bind is .575, 300lbs cracking pressure and 150 compression. I think my restriction is just my intake. Tmoss or trick flow will probably be my next step.And another thing, I don't plan to stay in budget, and I'll never sell the car. Unless I could go directly and buy a better foxbody.
