can anyone tell me what a good cam would be for my 70 maverick I don't wanna racing cam ,something with great street manners .I don't know what cam I have I just know its to much for my engine ,I bought the car earlier this yr and the guy dint know what the specs was he just said it was a blue racer brand.the car has headman long tube headers,edelbrock rpm intake unlite dist.600 holley and 3.00 rear gears with stock convertor.i had thought about the edelbrock performer-plus cam or maybe a voodoo line any ideas
You need to start with an honest assessment of what you really want from the car. What gears in the rear and what transmission do you have? The RPM intake might be a bit much for a street car, it doesn't start making power until 1500 and up.
and know what...bore, stroke, heads, carb, exhaust manifolds, rear gear, converter, intake and transmission. it all has to work together.
it has 9.1 comp. stock heads,its a flat tappet engine not roller,headmen long tube headers I wanna keep the 3.00 gears but more low end torque, I also want a good idle for stop light traffic .the tranny ia a c-4 the 268h is a good cam I just never driven a ford with that cam .
I have this one in my, swapped in a 2000 converter just for good measure... Unfortunately I'm yet to drive it but have no doubt that I'll have any issues... http://www.summitracing.com/parts/lun-10350700lk/overview/
krazy comet that's about what im looking for,i love the voodoo cams and im sure it will outperform the edelbrock performer cam
The Stroker McGurk syndrome strikes again. lol That 268 grind is going to be a tad too much cam for that motors head/compression, and gear. If you did run it.. a better stall speed and/or rear gear would be a must to really extend the power band where it will be most effective. Is this a 4 barrel intake/carb setup? I'd seriously consider stepping down 1 more notch to gain more average power and torque. Gaining the most "usable power".. is usually far better than gaining larger peak numbers or adding cool sounding lopes. In other words.. cam it to where you run it. Most here and everywhere else will tell you that wide ratio transmissions and taller gears don't keep you in a bigger cams sweet spot for very long. I'd recommend the extreme energy grinds because they tend to act bigger than their spec's show(they have faster ramps and more area under the curve).. and both peak and extended power range slightly through better scavenging effect. And trust me when I say.. that crappy little exhaust port needs all the help it can get. This is the one I'd choose for a setup like yours. Even moreso if it's just a 2v carb setup. http://www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=797&sb=2 And this would be the largest if it were a 4v setup. http://www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=798&sb=2 Despite the advertising.. both will give you a slightly noticable lope. Even moreso when you turn the idle down.. simply because you can. Throttle response will be excellent. I'd also consider advancing just about any grind you end up going with here since the static and dynamic compression increase can pay noticable dividend without killing topend potential. Good luck with it.
Summit lists that cam as 1000-5000 but Lunati has specs as idle to 5000... Also believe I've also seen 800-5000 as power range, should have a strong bottom end especially with my 2K converter... I bought mine from a ebay seller, was a dollar more than Summit but included a free Voodoo T-shirt... http://www.lunatipower.com/Product.aspx?id=2358
Now that one looks much more reasonable for the OP's setup than the 268 grind will ever be. Myself?.. I ALWAYS prefer extra exhaust duration and bit more overlap on these motors stock exhaust ports. It's the only recourse we have without firing up the grinder.
Yeah for sure, in the real world probably isn't enough difference in my Lunati and the 250/260 Comp you listed, but to me Lunati just sounds cooler...
Hi Comet. that's because you're looking at the wrong spec's. check out the .050 numbers and their spread between the typically advertised .005 numbers of both cams. The lunati grind will likely have greater variation between the two measure points. More aggressive lobes give more area under the curve and Comp's Extreme line is near as good as I've seen short of going with a custom grind. Of course.. there's probably other aggressive ramp designs being ground these days with all the head efficiency improvements we've seen these last several years. I just haven't bothered to look since I tend to like customized grinds anyways. EDIT: maybe not. spec's seem similar except for the wider LSA of the Lunati. I can't find the cam card to see actual timing spec's though and can only imagine that it would, could, might likely be a bit milder sounding.
lol.. old school.. and I kinda like it. Brings back fond memories. I used the same combo several times years ago of slightly "too big a cam" mixed with Rhoads bleed down lifters. Never was completely happy with their sound and they just don't rev like a short travel hydro when their oil metering goes to less than perfect. As is life.. there's always a compromise somewhere. Luckily it's not the 80's any more and technology marched on to give us roller technology. The OP's is already hydro roller and going to anything less than that will only be going backwards from a power potential perspective. Especially to cam's having huge spreads between their advertised .005 numbers and the more vivid .050 numbers. That's where air really starts to flow well enough and distinguishes the cool sounding posers from the real movers. Those old Crane/FMS/alphabet style cams just leave too much power on the table when compared to todays tech. IMO, to keep from going backwards too far here.. the M50 looks to be better suited to the build. Gear torque multiplication will be pretty low in this combo and the power leaching slushbox doesn't help matters much either. It's a light'ish car.. but if you overcam it and don't know how to tune it perfectly?.. it'll be a pig till that little motor can spin up a bit to build steam. If you're paying for your power?.. being nostalgic these days only handicaps you. It eventually just comes down to the matter of how much handicap you're willing to accept to maintain that nostalgia, is all. I say just respring it better and rev it till the heads run out.
