If I was you I'd wait until the Profilers are done and have a cam made to match it and the rest of your combo, or else after a few weeks of running it you'll be looking for another one anyways.

Not going with the Profilers gunna stick with the AFRs for a while after talking with Straub, Eric, and a few others looks like theres more power to be had with a cam change than with a head change.

Mike (Jones) designs cams and profiles. Just because the specs sound close does not mean they are the same cams. Jones has done quite a few cams for me and he knows his stuff. I'd trust him to build whatever I want.

Jones does do a good cam but so does Chris both have differing lobes and such but I have yet to see one be better than the other. Chris has been very helpful and gets back to me when he can which is very helpful. Jones is a great guy and I loved my old cam from him but just wondering bout this cam cus it would be a nice win win if it worked. Maybe I can just send it to Bullet and have it ground with a better lobe sep hummmmmm.

But most of us break out stuff in before we consider changing g something that isn't even dialed in all the way. I'm just giving you a hard time man.

I can take it boss im a big boy i dont mind criticism its welcome, i know i change crap alot but i have the time and I want it proper before the racing season gets here. Like I said why waste the time dialing in the wrong cam and why risk my nice forged new shortblock and AFRs with these lifters if their not what i should be running and putting it at risk ..... even though so far I have yet to find one thread of a morel 5372 failing even with bigger cams and more hp.

well I am pretty happy with it and my girl loves me so for xmas and bdays she gets me carparts and to offset the cost i sell the stuff I take off. But at some point i will go bigger bore dart block with big heads or big block but who knows I do need to get this one dialed in and thats probably why i figure if these lifters are on the edge id rather change em an if Im changing them change the cam. That way im tuning in the proper cam not wasting time dialing in one that I wont be keeping and 2 im not stressed that these lifters are gunna destroy my new motor that i put so much money into.

An just so you know ss the cam is not optimum for my combo that was straight from chris me having extra stroke leaves a lot to be desired he said stroke eats up duration alot or something like that. Heres a link to the camhttp://www.claysmithcams.com/sbc-377-to-390-cid-afr-190-to-210-head-max-power-6200-rpm-peak-torque-3600/ I had even saw a dyno sheet on there that showed it made 544 at 6300 http://www.claysmithcams.com/dyno-sheets-from-camshafts/ and thought i have more cr more stroke more cubes slightly smaller heads i should be bout there or better but chri says im probably bout 525 is im lucky lol haha

LMFAO come on now ss are any of us ever really happy I am plenty happy but always wanting to tinker who wants to stop and say "hey Im done and im happy." i cant think of anyone that has said that its a disease and im currently on meds, in theropy, and considering shock treatment lol.

Seems to me it has a bit more split than the AFR`s need. What is wrong with the cam you have in a 397? I`d like to hear the reasoning on that. I think it`s a great cam for your set up. The extra duration is just going to move your power band up a little and reduce low speed power which in a daily driver is not what you want. How many miles do you even have on this engine?

It is a decent cam but falls off fairly quick maxes about 5800-5900 it has lots of low and mid though. But both Chris and Mike have said optimum cam for the engine would be a 240/243 (jones) 240/244 (chris) both said round 580-600 lift and 108 lobe sep im assuming with 3 to 4 degrees advance ground in. I would like it to carry to after 6000 and start dying off round 6300.

Ok ss to make ur day I have a total of 1150 miles on the motor lol but in my defense I have to take the timing cover off to seal the oil pan and since the lifter thing has been bugging me figure i could change them same time and then if Im doing that why not the cam as well lol. But I do get what your saying ..... Im just trying to optimize the combo. I had thought the cam woulda been great but all i have heard is it needs more cam. An it is not a slug by any means it moves just seems to die off in the uppers pretty quick is all

No it was designed by chris for a 383-400 stroker using AFR heads not and the guy I bought all the engine stuff had got it with that in mind.

As for the gears i dont think that will make much of a difference at all its not alot bigger we r talking about 4 more intake degrees and 8 more exhaust and same lift in and .045 more lift on the exhaust side. But being ground on a 106 with 5 degrees advance id expect it comes on hard in the low rpms.

I cant seem to find weight for either the 4602 or the 5372 lifters but looking at them dont see a whole lot difference I know theres different valving and a .750 wheel vs the .700 wheel not to mention I think the axle is bigger too.

Nice to hear about the morels Ive been a bit nervous about that.

I live at 4500 ft above sea level so we can get away with 11.5 heck i ran 12.3 to 1 in my old LS motor on reg premium pump with no probs. My cranking pressure at this alt is right round 198-200 psi, and so far zero problems with premium gas

An i didnt say it would work I said it would be cool to get the better lifters and a better cam in one shot rather than a cam that wont work is all. I have talked to Chris and he said he will run some numbers and give me his thoughts on it when he gets a chance hes pretty backed up right now. When i asked for a custom cam he speced something pretty close in my book a 240/244 on a 108 with 104 icl and like 590 lift so this is a lil less intake dur bout same ex and same lift on a lil tighter lobe sep haha just my thoughts

 

[imp-oster]

havent heard back from him on it yet left a message but Im waiting to hear back from him i know hes a busy guy and so not gunna keep calling an calling haha but thought id put it up to hear from a few others as well that may have used a similar cam in a street car. I did call bullet thought who are the ones that ground it according to the cam card. it was speced for a 427 sbc autocross car who is going to a LS series motor.
