More help needed, I'm having short block done 496 eagle rotating assy, would like 10.5-1 comp, don't know what roller cam i should get (would like a good thump with out loosing power) nor what heads to get? I do want to run this on pump gas, I do already have victor jr intake (oval) and 750dp which seems to small to me but this is what the machine shop is recomending I run. This will mainly be street application but would like to play on the strip also, it's going in my 74 TA which weighs around 3700lbs. I would like to at least run low 11's if not break into the 10's. Power glide with a 3500 stall. 4.11 gears .

As always any advice is appreicated
thanks

I always used to be REAL conservative when choosing street cams.Never made the power I wanted either.Always ended up building real torquey motors that wouldn't pull past 5000 rpm at all.I don't know what head your are running but you said the intake is oval.With that many cubic inches and oval ports,I don't think you should have any problems making some good low rpm power.As far as a cam,the cam I got in my car now is a Comp solid roller 308AR.It is a 652 lift cam with 308 adv dur and I think the .050 is 260 something.My car weighs right at 3400 lbs with me in it.I was running 4.88 gears on a 28x9 slick with 11.2 comp and a 3800 stall.When I got that cam I thought I had bought a monster race piece.I had never ran more than a 575 lift at that time.Found out that my "monster " cam,a cam I thought would kill bottom end on the street,is what I had been wanting all along.Personally,I belive that a 650+ lift cam with 260+ duration is a great place to start for a STRONG street cam.It's pretty rough for a daily driver,but for the occasoinal burn the streets up,I love it.Pulls HARD from 3000 all the way to 7000 rpm's.Don't be scared to go big!!!But it all really depends on how radical you want it and how much you plan on driving it.But don't be scared that alot of duration might kill your bottom end.It's all different with a roller

P.S. My car runs on 93 octane with a little 110 mixed in(4 gallons of 93+1 gallon of 110) your 10.5 should be fine for pump gas.And the 750 dp,I run a Dominator.the motor uses up everything my 1050 can throw at it.Actually I was having to jet it down so I could hook on my baby slix.

CAR IS TOO HEAVY FOR A GLIDE IN MY OPINION.

we run a glide in our almost street trim 71 nova with big boy ( me @ 280lbs ) driving and it tips the scales at around 3900 me included.
Never had any troubles with the tranny.

I like rectangle ports but thats my 2 cents, but back in 1978 building my
first sbc, chet herbert (doug herberts dad) told me that on a motor for
street you don't want to go over .500 lift sbc, .600 lift bbc, on the street.
because of the daily driving. i'm using a solid mechanical roller cam
with a .636 lift, mostly strip, very little street. but my friend has a
nova 283 w/a cam that has a .750 lift and it sounds ratical on the street,
more lift than my bbc cam, so much for the rules of the street 8)

im guessing a hydraulic roller.you can ask udharold here on the forum about cam selection.hes very knowledgeable on cam selection.as far as heads try to go no bigger than 320 cc for a street/strip head.lots of them out there.check ebay(DONT BUY USED PARTS!!!)PATRIOT HEADS ARE GETTING ATTENTION.afr heads are always on top of my list but lil pricey.but remember you get what you pay for!!!!keep it fairly simple and if you wanna lil more you can always throw a lil spray in her.good luck,russ

I agree with Russ on this one, he's a winner here. Every time I buy used engine parts, they end up costing more to fix them, than it would have cost to buy new. Just my .02
