How much N/A Hp are you making with GOOD dove heads?

ok I thought the 9.90 was the dove motor in question.

9.90 is doable with any BBF head and no NOS, ,ENGINE ONLY, even the D2VE'S.

Very true, I was questioning a 760hp motor with a 175 "only" running a 9.90.

lots of confusion.......................lol

One of our cars just went 9.59@ 141.45 in April in a SS 2900# 28x10.5 with a 508 with max effort D0VES. Given the weight and MPH I figure 800ish. My car makes around 650-675 N/A, but its not really built to run N/A so the camshaft and a couple other thing hurt it a touch. Its a 460 stock shortblock w/ a flat tappet. Im sure there are guys that have made more, but I figure those 2 examples are acceptable.

barney whats your build? you have cast pistons correct? 650-675 hp is impressive. thanks

It has a big hit on it.. Its a tube car correct?

yes cast piston, stock crank, rods, pistons. D0VE head w/ some work.

I run big hits at times with it, Its a 3085# back half car. The other car is a stock suspension car and runs mid 9s N/A

Cool... My car is a stock susp. car with little ol 10.5s on it..

You can go fast on SS stuff, it just takes some work.

yeah so far so good. guess sence Im on a budget Im going to try and scoop the doove heads... Whats the weight difference going to be? also is $1200 fair for them?

if they are all together not apart and have the big valves not stock valves they may be worth it I have about $900 in mine building them with valves,springs,machine work,porting,and my doves was gave to me.

They really are top notch heads for being an iron head. How much more do the weigh compaired to my aluminum heads?

I might be wrong but I think I read some where on here or the other site you would save about 80#s going with aluminum over cast iron I maybe wrong like I said.

80#s is about right. Blake did a swap from the ported streets to a set of iron CJ's that he ported...............I won't elaborate any more on that topic lol.

Yeah I did some reading and found around 35#s each difference

For the money i would get a set of SCJ heads from Lem. D0VE heads can work well, but they will never work as well as a aluminun like a SCJ or Street. Dont get me wrong they are a pretty good iron casting, you could also look into a PI head, or Iron CJ, but they are harder to find.

Don't really want to change pistons.

TFS Streets, Eldelbrocks, or older Motorsport A429's have same valve angles as the factory heads no need to change pistons

Not sure if my pistons will work with the SCJ heads.. Im thinking they will but..? Here is a pic of my short block..

Correct.

Those pistons look like trw or speedpro domes so no they will not work with scj heads without cutting new valve notches

I was making 614hp with Scotties heads. This was many years ago (about eight) and I know he's picked up on far more tricks since then.

Answering your question, 720-750 hp is going to be max with around 13-14 to 1 compression and a 270-ish cam, sportsman type engine. You start adding a dry-sump, more compression, and a couple of more tricks, and you might be able to to get it 775, but you're talking about a high maintaince motor, and 15-20K price tag. Most ain't willing to to that with stock heads.

Hope that helps,
