Without doing enough research, I bought Comp Cams 986-16 double beehive springs, and didn't realize the heads would need a little machining for these to work, so now I'm back to square one.

Whats a good, no machinework required, stronger valvespring that'll work in my E7's, and handle an X-cam?

Does it have a spring recomendation on the cam card? If not, call Ford Racing and see what they recommend for a spring.

Why an X cam?

that's a lot of cam for stock heads.

I planned on GT-40's originally, but had things come up and I couldn't quite scrounge up the money for them. Instead I got a free set of E7's, and have been porting them myself over the last couple weeks. I know it's too much cam for the heads, but I'm planning to build the stock motor thats in my car as a 347 over next winter, while these heads and cam will go into the recently rebuilt roller shortblock I have in the garage.

Somebody recommended these.. They say they are good to .520 lift, but the X-cam is .542. Are they "good enough"?

That cam is 20 year old technology and won't be impressive at all. In a 347 it won't be right either. You'd be better off putting heads and intake and the correct cam in a 302.

Valve springs are either correct or incorrect, and never good enough. If you use a .542 lift cam with springs that are only good for .520 lift, you will end up with a pile of broken junk.

X cam is too big for gt40 heads.

When building a stroker, there are too many variables... bore and storke, cid, what heads, what compression, what kind of exhaust, driveablility, track or street use, what gear your running, auto or stick.... only one way to make the cam work for you...

I'll let Darrell tell you what he thinks about custom cams.

[Silversixspeed]

Not sure if this makes a difference, but the car is carbed, is my "daily driver" on nice days, manual, and streetability isn't a huge issue for me. I only drive about 7 miles total round trip in a day. I'm also spraying a 100 shot, and will hopefully bump it to 125 or 150 with this other motor.

So, would I be best off getting a different cam? I'd like something that'll work for these E7's (too big doesn't bother me much), and something that'd work well with GT40's.. The intake I have now is an Edelbrock 289 Performer, I'm also wondering if this needs upgrading?

I wouldn't use either.

I would get better heads (that you can swap onto your new motor later)

and run your stock cam because a custom grind now that you will just toss out later is silly

Well I wouldn't toss it out, I'm just looking for something that'll work ok with these heads, but then really come alive when I get something better, most likely GT40's. Obviously I'd get better heads if the opportunity arrose, but being a full-time college student on my own making slightly more than minimum wage pretty much shreds that possibility.

[superbean]

well I understand the college thing totally lol

Right now I'm running a tfs stage 3 cam in my drag car.. and it's really really overkill for my setup, but I'm too poor to change it.

Have you notched your pistons? X cam has a bunch of lift and may interfere

[Silversixspeed]

The shortblock I bought had an X cam in it before, and the pistons were notched out a bit. I'd obviously do the clay mock-up before setting bolting everything together.

So, would I be best of "trading" this cam for something else? If so, can someone point me in the right direction? Someone to talk to?

[flyin ryan]

I wouldn't waste your time with that big of a cam if your stickin with the e7's..
If you want off the shelf then sell it and pickup a used tfs stage1 or e or b cams that are dated but still run decent in stockish motors

but I would suggest on looking at what goals you want to meet with this then build around it

[Silversixspeed]

I will make a seperate post shortly, asking more about a heads/cam choice, since I don't think I'd get many hits in this thread. Thanks guys!
