Schurters LT1 you said Bret had a Dyno graph showing the HP and TQ curves of different cams on different LSA's (I guess using the same duration and Lobes). Do you care to PM me that Graph or graphs.
I sure do see alot of people making a lot of HP and TQ using the smaller 22X duration cams with 114-115 LSA cams. Plus the driveability would seem to be better.
Thanks man

 

the graph is my cam compared to the 224/234 high lift cam everyone run's....this cam made 15-20 hp more through the power band, trust me talk to him, this cam was made over a year ago..he may think in diff ways now in witch you can make more power/tq......

Talk to Bret, good Luck

 

I have the same fmic as you and I'm glad to see your making such big numbers with it. I was a little worried that it might restrict cfm above 500 HP.

 

I made a few pulls on the dyno before i put the meth on and my IAT were 40* at the end of the pull......

 

Cam motion just recommened me a cam for the 383.
232/239 114LSA 4+degrees of advance
.570 .582 with 1.6RR's In between the aggresiveness of the magnum and XE grinds. I am thinking about use this cam, but I am wondering if it is too Big for my daily driver Blower car???? I was advised to run 150 on the seat and 420 open.

 

From what i have read, you would like more of a split 10-14* for a blower car, But Cam motion No's more about cam then i do

As for being to big i would say no that cam i think would be miled in a 383, my cam is a little larger and i have a 355 and i drive my car every day and i think it is fine.....

I have about the same on the seat for springs as well, with comp R's, who's ever cam you pick run what they tell you as for spring they should no best...

The reason i keep on saying Bret is because he has a bunch of cam's out there in the LT1 land and i think he has a good idea on what these car like...

Who ever you pick make sure you tell them your combo IE: intake, heads/flow numbers, exhaust, and so on this way you are going to get the best cam for your combo at the end of the day....and the number that you want...

 

BTW, this cam was supposd to make 700rwhp in a 383ci engine... looks like Jeremy accomplished that with less cubes. I wanna see final numbers, hurry up already!

 

Actually what nobody ever figures out is that LOW RPM, HIGH VACUUM TQ is what makes a car driveable, not wide LSA's. Wide LSA's hurt TQ most times due where it places the valve events and there is only so much you can do with advancing the cam before it really screws the exhaust events up. Blower motors with a good exhaust can still have a narrow LSA and work since they don't have backpressure like a turbo.

I have a customer with a 383 TFS heads from Lloyd and a emissions legal setup running low 10's in the heat 3500+lbs, so I'm sure this cam is 100% driveable in daily use.

Jeremy, e-mail that video to me!

Thanks,

Bret

 

wow that car is sick. Congrats on the dyno #'s!

 

Nice nbr... very impressed

Maybe I did a mistake swapping the cc306 för a 227/239 114 custom cam

 

You'll be fine.

 

WOW Those are crazy numbers

 

LOL thanks Bud ...i will be going back soon........I really don't care at this point about the number YES they are very nice i just want to nail down the AFR and timing....

 

i KNow this is an old threat but dixd you ever end up passing smog with this set up??

 

I doubt it with that cam. I run a 234/250 and I know it wouldn't pass smog.
