I have no low apply in mine. The builder didn’t tell me what he was doing. I trusted him to do me right. He was an old timer trans builder. Art Carr. He just passed this year.

I have a supposed 3000 stall 11 inch in mine. But if I lock it in 3rd and gas it at 2200 it only flashes to about 2700. In first it will light the tires even at less than full throttle. I’m betting a good 10 or 9.5 would improve performance but for me is it worth the cost.

I love those cars. The interiors just rock.

If you think about it. As the lobes became more aggressive the seat and over the nose pressures have increased. Most of the cams I’ve seen that were going flat all started on the nose. A cam with a 350# spring and a 1.5 rocker put 525# on a maybe .200 diameter contact patch. That is about .03 of...

Yup I’m thinking a 2800 to 3000 stall that has low slip above lockup. My car weighs 3400 empty with 2 gal of fuel. And I’m running 3.73s with 275/60/15 tires. Right now Cooper cobras but some sort of street drag radial would be appropriate. My thoughts are that a lot of this is dependent upon...

I’m thinking street mostly. Sound tough at cruise night and not need to shift beyond maybe 6k if raced.

I believe that the vast majority of the guys on this forum have either stock or lightly ported iron heads. A few have stealths and less still Trick Flows or Indy’s. That’s my main thought process. Restricted flow for the given displacement. I’m loving the feedback. Pumping up the midrange is my...

I agree. A [email protected] with a 106 would have a tremendous amount of overlap. It would blow too much charge right out the exhaust valve on overlap. Don’t forget my main premise for the thread was a low compression, under 10.5 440 with heads flowing approximately 270 at .500 lift. That seems to be a...

Yup he’s a wizard for sure. He brought a lot of tech smarts to Comp’s lineup.

I hadn’t seen the Isky one. But John K was my customer at Scat. I was their senior engine tech. Worked with drag,nascar,road race and factories. I really learned a lot working with these teams and guys from the factories. I had lots of guys we helped on the Engine Masters challenge. John used a...

So the cam I’m using as an example here has pretty aggressive ramps. Only 30 degrees of ramp so that means 15 degrees from .020 rocker clearance valve on the seat till valve hits .050. Same for closing. Tight LSA but only 84 degrees of overlap. Don’t get me wrong. I know on a motor with good...

I’ve gotta go watch his video on this.

I agree with this. Street cars need mid range. My numbers are 3 to 6.5k. Pump gas. 3000 converter. My 440 has 270 to 280 Cfm at .500 to .600 lift. Not a lot for a big block. So a fat mid range would be fun if you could hook it up.

Don’t know. It’s been 10 years since built one. But one is still running 287/295 adv 256/264 @050. I’m just thinking that if I build this block with a Scat lightweight stroker kit then I might have a cam ground to bump up the mid range. I think this will be my last motor and car so I might as...

Oil contamination? Retarding the cam will drop cranking pressure. Hope your problems are fixed.

You’re right on target. I found that an 11 to 1, tight quench .027, 3.75 stroke motor with a wide [ for a sbc 4.185 bore]calmed down the tendency to ping on CA’s 91 summer blend. Since most circle trackers at the time running 400s were single gear for the whole track the rev range worked out to...

He’s a 4 speed I believe.

I’m new to mopar big blocks. Back in the day I built quite a few SBC 400s. Typical 30 over flat tops, 64cc iron world products heads. With my home port jobs they would hit from 280 to 300 depending on how extensive the customer wanted to pay for. After trying a lot of cams over the years I...

I think your cam is a bit small but not outrageously so. You said something that made me think otherwise on a possible answer. You said if you dump the clutch and nail the gas you can roast the tires. But if you hook it up by being easy on the gas and clutch then hammer it you don’t spin. What...

I’m running a 440, 10.5, stealths,rpm with 750dp. My cam is hyd ft 242@050 and 500 lift, 108 LSA. Boils the tires.
