I had that cam, and it's a bit big for street use, but works decent with a single plane manifold(mine was a torker II)

here's teh desktop dyno graph with a 750 cfm carb, 800 had a higher peak but was spiked

Dont see a picture bro, its probably just this junk computer.

Also, im thinkin 434 now. So 4" stroke. Eagle makes some h beam rods that clear up to 4"s. However im still scared of clearence issues other than the oil pan. Will there be any clearance issues with the crank hitting the block or the rods hitting the block? If not a 4" stroke crank costs the same as a 3.75 so i might as well go all out. What do you think?

Never mind found out the answer...ill keep ya updated on the beast.

will it fit?

It would fit, but gotta do a **** load of clearancing. Gets really expensive so not worth it in my book.

ooh and by the way....eagle is prolly the best brand to buy as far as quality when it comes to bottom end parts...in my opinion.

Ive heard quite the opposite actually.

thats just in my opinion. thats what im running in my motor.....umm....other than them the next brand i would look at would be scat. it all depends on the money you want to spend i guess.

a ton of people run scat cranks. and a ton of people run eagle rods. thats what it seems like to me.

im running all eagle stuff in mine....its all your preference i guess. i just like eagle.

exactly both are decent companies and both have failures

ya i mean the rods and crank are either gonna be eagle or scat. Since those are the forged pieces that are within a "reasonable" price. However ive heard a lot more horror storys about eagle than i have scat which i why im gonna get a scat crank. Rods...who knows might just be eagle but most likely scat as well.

Anybody have a "what they think" is a better cam. Everything else im already dead set on but the cam im not 100 percent sure of yet. Must be solid roller tho. Lemme know guys. Streetability doesnt really matter. Should be within the 3500-7500 rpm range duration wise. Also under .660 lift and over 600 lift with either 1.5 or 1.6 ratio rockers. Lemme know fellas. Also lobe seperation at 106/108 range.

Been lookin at these ones as well arch. Can u slap these on desktop dyno 4 me.

270-118911
Adv. Duration: 284°/292°
Gross Lift: .630''/.630''
RPM Range: 3500-7200

638-50103

I know its a lota work arch but u being my best friend n all i figured u wouldnt mind :D :lolsign:

what I did was call lunati and talk to one of their tech guys great feedback gave me a size that made good power (just for fun I called crane and they were withing a few hundreths so pretty close on both)

desktop dyno desktop dyno :D pwwweeez throw em on there

the first and third cams made about the same peak power but the curve was flatter with the first, about the same power as the first dyno I did for you. increasing the exhaust to .655 flattens it out for about 1000 rpm at 550 hp with the .640 it's about 500 rpm

and the 800 cfm carb has the best curve

Soooooo which was best lol

Im just confused cuz of the 1st and 3rd cam one but i donno if u mean the 1st cam i chose (not listed on that list above) or the 1st cam out of the ones there. Just copy paste specs 4 me pweez. Really appreciate it arch.

1st on the list the graph didn't want to come out legible for some reason
