Why not go the other way?

Like a solid roller, remove the hydraulic element, and go to a much smaller SR lobe as this only peaked at 6000RPM..

Looking through the comp book:

IN: 4871 the XE 224@50 lobe
EX: 1476 the HE 244@50 lobe ... 109 LSA something like that
Well its all hypothetical now since the engine is gone. But, as nice as a SR is for testing it just wouldnt be in the budget for "Dale". And my thought was to see if peak hp rpm could be pushed up with more area....how much and how the curve looked at and around it. I also would like to see how the bottom of the curve stood up to a chunk more duration thrown at it.

good post levis,
the reality is it is tough to get a genuine 500hp out of a pump gas 10.5:1 small block anything,we all know some good fellows on this forum punch way above,and through testing and actually building engines they get the job done and post there results good or bad.
i spend a lot of time at my local track and all i hear is my engine makes 600 plus blah blah and @ 3400 pounds runs mid 11s @118 MPH.OR SO
thats probably 100 hp shy,anyway i should not be raving on,just felt like having a whinge. :roll:

The engine I mentioned was an underperforming unit in the car ,, I don't know if it was converter , gear , what ,, I have to wonder if it was a intake velocity thing ,, yes it made 500hp on a dyno , no timer on a dyno , just hard to nail down exactly , but if I was a betting man I would say the head was a little big ,, this shop has done other motors that did less of a dyno number and were .50 quicker in the 1/8 in a similar car / set up

good point,
i actually had a phone conversation with a pretty smart guy from the forum here a couple of weeks ago and shift recovery came up in the conversation,
even for own limited knowledge and experience have gone to smaller heads and smaller cams with surprising time slips,my car is running within a few tenths in the 1/8 mile compared when i had a bigger head/cam and higher rpm application

Do tyres hook better than tires Steve??? I was a terror at this kids age(17) with a high 14 second car. But fortunately, Brenden seems a more calm and responsible than I was. It should be a 120mph car in reasonable air.

C H A D,
you had me second guessing on my spelling lol
Australian spelling - tyres
American spelling - tires
both mean round rubber things that produce white smoke (burnout)
Australian spelling - tires- exhausted,buggered,knackered,f**ked,needs a rest etc
this is hilarious,never in all my years have i noticed this. :D

It used a 6AL and a MSD billet on the dyno, Braswell 1.490 x 1.75 carb if I remember right. He has a used digital 6 box for the car and is buying a new carb with similar dimensions for the car.

Would have been nice to have his carb for the dyno.....but I had him get an O² bung added to his header so we can get it tuned up a bit quicker in the car. Not sure what to expect with the new Holley carb.
