What cam would you guys recommend, currently my setup is a 302 (roller block out of a 92 mustang), Edelbrock aluminum heads (2.02 intake valves), 1.6 roller rockers, weiand intake, 600 cfm carb. It currently has the stock cam in it, I don't really want to have to change the rockers and springs. I was thinking about the ford B cam, I want something with a nice lope to it. What do you reccommend? Thanks
The Trick Flow Stage 1 has a nice little rump, rump and pulls strong from 2500-6000... With either cam a 2400-3000 stall converter is recommended...
The B cam has a healthier lope to it than the specs seem to show, it's even better run with 1.7 rockers to bring the valve lift to .510. Excellant cam for those on a budget as you can pick em up for as little as $50
Stage 2 is a nice cam. Check piston to valve clearance to be sure.Trick flow suggests 0.080 on intake side 0.100 on exhaust.
I like comp cams "extreme energy" lobes. More aggressive ramps will give you more area under the curve and tighter LSA will give you the low-midrange torque along with the inherent lope you're after. And.. If you go with anything much above a 260 degree cam.. you'll be better off to get rid of those cheap'ish springs that Edybrock included with those heads. I've used tons of them heads on various motors through the years and they're not the best springs for aggressive lobed hydraulic cams and they also lose too much pressure over time. I'd stay at.. or slightly above.. 125-130 seat pressures even on a milder roller build such as this. The bee-hives give more rpm at lower pressures over the traditional damper style spring too.
Interesting, it sounds like I need to change the spring regardless... I was thinking I could use the springs from the Edelbrock heads with the B cam but it sounds like I would be better off changing them. Thanks for all the recommendations
If you're going to try the B cam, I'd do it with the springs you've got now and see how it does before investing in more springs, The B cam is fine with the stock HO springs up to about 5500 rpms. If you want to rev it higher, get better roller lifters (I went with Comp's O.E. rollers ) and springs.
I think baddad is right on. that little B cam should be fine with the edlebrocks off the shelf seat pressure. that cam will run out well before those springs will anyways. some spec's here http://www.roushyatesparts.com/v/vspfiles/assets/images/ford_racing_camshafts.pdf But if you want to rev it more than every once in a while with a more agressive cam(270+).. I'd get better springs. From experience with similar comp cam grinds in other motor builds.. I know this stout little cam will wake that little motors mid-range pull right up due to the tighter LSA. And.. while likely still giving you the bonus of pretty decent off-idle/low speed torque and mileage beyond what you probably already have. Plus you'll get that.. "not quite stock anymore".. kinda sound from it at idle. Next step up in duration would sound even racier! http://www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=1044&sb=2 Also.. when I googled quickly for that b cams spec's I ran across this little thread. May be worth the read to get an idea of others experience using it. Also ton's of 5.0 sites out there to pool knowledge from. http://www.allfordmustangs.com/forums/5-0l-tech/193151-both-b303-e303-camshaft-specs.html
Read my sig. The springs that come on the Edelbrock heads are actually rated a few pounds higher than Comp's recomended springs.
that's a healthy little street cam right there. It seems odd to me that they make the XE for the computer controlled 5.0 stuff.. but not the carbs. The EFI's required wider LSA will likely give a bit of a broader power curve and help with potential clearance issues too. did you run into any valve to piston clearance issues there?
No, but I used to run a much larger duration cam and had flycut the pistons for that. I'm sure flycutting wouldn't have been required if I had started with this cam. But, you always need to degree the cam and check piston-to-valve clearance with any cam swap.
Just FYI, the EFI cams work better with carbs than the narrower LSA cams do. I've run the stock F4TE truck cam with a carb and it works great, actully so good, you can go out in 25*F weather and crank the engine with no choke and no pump shot and it'll fire up and idle on it's own, exactly like an EFI motor would do. All the Ford Alpahabet cams are technically EFI cams with wider LSA's
