Don,

Brian recently built a 360, stock crank/rods/KB107's, 2.02 RHS, Comp XE275HL hyd cam, Air Gap, 750 DP, headers.

Made right at 430hp and 440tq

Not a crazy build and capable of 11.60-11.80's in a well set up car, that I know you are more than capable of putting together.

There are a bunch of different flavors of these heads floating around out there. Make sure you pay attention to the parts that they come with, there is a big difference.

Thanks, good advice.

Actually am kinda leaning toward a 360, it will make a little more torque than a 340, and me being as big as i am and the car being full weight, it might ultimately 60 foot better with a 360 than a 340, and i kind find a block easier. Guessing it will need to make about 460 or 470 with a 904 to get me where i want to get.

Probably like a tti header, weiand excellerator( i love that intake.. and the 318 that was in the demon when i bought it has one already sitting on the motor), proform 750, maybe a hughes flat tappet somewhere about 246/252 ish at 50, that will have a decent little thump, a ptc 9.5 convertor, 4.10 gear and leafs and 8 inch wheels and 10 inch tires.

That's a bunch more cam than you need...

I think the 275hl intake is 231 at .050. I'd bet that cam you state would get you a bunch closer to the 460-475hp mark.

Hard to beat the RHS on a bang for the buck basis.

kinda the reason i was thinking a cam in the mid 240's at 50 is because i want a little thump, and something like that on a 108 will sound pretty cool. Also my little brother has a 360 in his 66 Dart with Eddies on it. Its about 9.5-10.1 compression and runs pretty decently, he has been 11.38 with it at about 117 at 3300 pounds( bone stock interior and no fiberglass with a 904) he has too big of a cam in his car( 258-264) yet it still runs respectable with his 8 inch convertor, so i figure something 10 degrees smaller and otherwise similar combo's should be a nice compromise. He has a 750 and an excellerator on his( that i gave him) and dinky headers.

I see Hughes makes a 246/252 thats ground on a 106, with about the correct lift with a 1.6 rocker. With that tight of LSA it should sound choppy.

I think you're on the right track, Don! I am looking at about the same cam 258-ish/265-ish for the 408 after talking to Bullet. Tim and I discussed a 360 combo as well and he had the same thought; trim about 10 degrees off for the 40 cubic inch diff.

Now I have questions about his ride: Are the Eddy's "stock"? What gear/tire? Street driven?? What is the converter flash/stall? It sounds like it runs REAL good at that weight.

It is a 66 Dart Gt with the factory bucket seat interior intact, bone stock body, and a 6 point bar.My little bro probably weighs 250, about 50 less than me. Has 27 by 9..?? QTP'S on it. Ce 3 ways all around and leafs. The heads have been professionally fully ported, but frankly the car for whatever reason didnt run hardly any better than it did before they were ported, for whatever reason. My GUESS is that with chamber work and such done, it lowered his already low compression even more( have no guess as to what it actually is currently, figured it close to 10 to 1 initially, so that perhaps made that big cam even more wrong for the combination. He has small tube cheapie headers on it, my old mechanical 750 holley and excellerator, and a 4.10 gear with a 4800ish flash ptc convertor. I actually thought the car should run 11 teens at worst with those ported heads on it, but the largeish cam, suspected low compression and such may mean he doesnt have a ton of cyl pressure, at least that is what i told him i thought was going on. He hardly ever races it anymore, so i doubt he will ever do anything about it.

I like that area of cam you are talking about for the 408. Probably the best running combo for what it was that i have had was similar. 416,11.5ish compression, excellerator, race demon 1025rs, tti dinky 1/58 to 1 3/4 headers, 4.30 gear, 5000 flash convertor. My cam Dwayne Porter helped me out with and i loved it..Comp flat tappet 260/266 on a 107 in at 104, 598/623 gross lift with 1.6 rockers. That all steel car with the stock hood still on it, full bench interior, and me shifting it off the column ran 10.74 with mildly ported( stage 2) eddies from Hensley, car weighed an honest 3450 pounds with me in it,and a full fuel cell which i always run with, the Dana and 727 and a mild steel cage. On several occasions i drove it 70 miles round trip and raced it at US131. Had i had those heads done full bore, it would definately have run 10.50's with the bench and column shift still. But i sold the whole top end and went w5's

I have that same cam in my 360 with the 1.6 rockers my car is street- strip and i really like it so far.
