Guest Mike Posted September 8, 2006 Share Posted September 8, 2006 Hi All, I'm ready to make a few improvements to my old SBC 350. A new cam and heads are my first changes. Of course, I'll match everything to my performance goals... I'm afraid grumpyvette will yell at me if I don't:icon50: I'm ashamed to admit that I'm such a coward:oops: Okay, here's my QUESTION... Has anyone tried Camshaft Innovations (Cam Master Jay)? He custom grinds cams and machines heads. Or am I better off sticking with Crane or Competition? I hope to solicit some help from grumpy to match components and tune this engine right so I don't mess it up:confused2 Hey there grumpy... this is for you:shifty: ...just kidding:razz: Many Thanks all!!!!

jnjdragracing Posted September 8, 2006 Share Posted September 8, 2006 I have used Comp Cams, and was very satisfied with them. They have reground the cam I am running now.

dr_hunt Posted September 8, 2006 Share Posted September 8, 2006 Grumpy is right, I used a brand x grinder to grind me a cam, worked ok, but not like the name brand cams. I like isky cams, crower and comp and run all three. Unlike grumpy, I don't like crane that much, due to similar experiences that grumpy is talking about. The important thing to remember is that people make up the company, not the other way around. So if you deal with a stooge, you'll probably get the wrong stuff.

I'll stick with a big name brand. Comp seems to come up most often so that's likely who I'll use. I agree that "people" make the company what it is... good or bad. I'm also "nearly" convinced to go with dual quad carbs instead of triple deuces. I just really want that look. The 3x2's look nothing like the original GTO with 6 Webers and 12 velocity stacks but, with the right breather, they look very similar to Ferr_ri's street versions of the era with 3 Webers.

Please keep in mind that I must keep my sanity with cost vs. performance/looks :^) You've already convinced me that dual quads is a good compromise, Grumpy. I TRUST your judgment and this is my decision. I don't have $5K to invest in an 8 individual throttle body crossram system... though this would be the ULTIMATE :^) What I need to know now is... what is the best DUAL QUAD setup for my mid/mild SBC 350?

LS1 240Z Posted September 10, 2006 Share Posted September 10, 2006 dont use comp cams. they are idiots, you call them up and tell them you want a cam with x specs and they will tell you it cant be done and recomend something terrible. (expecialy if you order up some big LSx cam) most of the small companies dont grind their own cams, they have comp cams grind them for them. this is the way it is with thunder racing and texas speed, they both just have comp cams grind all their cams. you can get a cam ground directly from comp, but the people you will talk with will be idiots.

Aren't smaller 4bbl carbs available than 500 CFM. I'm afraid 1000 CFM will overwhelm this motor. I thought Holley made 360 CFM 4bbl carbs. Wouldn't two of these be ideal for my 350 SBC?

jakeshoe Posted September 11, 2006 Share Posted September 11, 2006 Crower has much better tech support than Comp, and Quality control. I personally use a small cam grinder in Tacoma, Washington for 80% of the stuff I do. Delta Camshaft http://www.deltacam.com There website isn't fancy, they cater to local racers and engine remanufacturers/machine shops. I often use there reground camshafts in my own personal motors, I have used probably 100-200 of their camshafts ( I used to street/strip and racing build engines in the Tacoma area) without issue. They can grind a cam from quite a few different profiles, and they use Comp Cams masters for alot of their stuff. That is, if you call wanting a SBC hyd flat camshaft with a 280* adv duration and ~230*@.050", you will get a cam ground using the same master lobe (it is attached to the cam grinding machine to grind the lobe to a specific profile) as the one Comp Cams uses for their 280H Magnum cam. They also have pretty good prices on quality lifters, springs, pushrods, etc.. They stock alot of Comp stuff too. I usually talk to Scott.

COZY Z COLE Posted September 11, 2006 Share Posted September 11, 2006 All this dual quad talk made me think of a couple of great muscle car Beach Boy songs. 1.) 409... A line in it is " My four speed, dual quad, posi-traction 409." "She's real fine my 409." 2.) Shutdown... a song of a race between a Stingray and a Super stock Dodge. " Pedal's to the floor hear the dual quads drink.And now the Four-thirteen's lead is starting to shrink.He's hot with Ram Induction but it's understood. I got a fuel injected engine sitting under my hood. Shut it off, Shut it off, Buddy now I shut you down." LARRY Quote Link to comment Share on other sites More sharing options...
dr_hunt Posted September 11, 2006 Share Posted September 11, 2006 Yeah, I think comp is too big for their britches. When I called for a cam recommendation for the TT motor, I got a guy, who kept talking to some guy next to him, and he finally gave me a couple of lobe profiles to request, etc, etc. Ok, so I give that info to Edwards Engines for them to order the cam since it's cheaper through them than if I buy it direct from comp. They call me about a week later and tell me that those lobe patterns were incorrect and some master cam technician recommended new lobe patterns and that they ordered those instead. So, I was like ok, whatever. Well, I ordered 4/7 swap, cast iron gear, custom solid roller, what I got was regular firing order, cast iron gear, custom solid roller. So, no biggie I guess, I just decided to run it like that. The springs for this lobe profile have 250lb seat pressure and some un-godly open pressure that I can't even remember right now, but like 700lb open if I remember correctly. I've never had a problem with crower or isky, but I have with crane, but at one time crane was a bigger outfit than comp. Now I think comp is bigger than crane, or at least they act like a bureaucratic giant anyway. My main complaint with crane is that they prefer wide lobe centers and I grew up circle tracking using tight lobe centers like 104 and 106 not 114. Anyway they kept recommending these screwy IMO cams for circle track engines that had wide lobe centers, tried one and it totally sucked off the corners and was a dog. Changed cams to Isky with a 104 and kicked some bootie! Amazing what a cam can do for a motor. Quote Link to comment Share on other sites More sharing options...
