Bigger cam?

[jmortensen]

You asked for it:

Here's the old build: http://videos.streetfire.net/video/2000-autox-indisde-and-outside-I-think-my_8051.htm In that form I placed 2nd out of 175 cars at an autox, 2nd out of 65 at a track day, and 12th overall at a Porsche Owners Club time trial (fastest non-Porsche, 170+ cars total).

And here's what I've been working on for the last few years:

What you're not seeing there is the all aluminum 5.3L V8, the 10" front and 12" rear wheels, the Hoosier 23x9.5x15 and 23.5x12x15 slicks, IMSA rear flares, the 12" brakes, fiberglass hood and hatch, etc. Sure it's not done yet. But when it is, I think I'll take you up on your challenge. 2200 lbs, 5.3L V8 with ~350 whp.

This isn't about who has the biggest **** though, its about whether or not you NEED to replace the rockers when you replace the cam. In my experience (not theory) you do NOT need to replace or resurface the rockers. Experience > theory. Show me the post from someone lamenting the fact that they didn't resurface the rockers.

One more thing I did repeatedly that you're not supposed to do is pull the cam towers without pulling the head. Did it BOTH times I replaced the camshaft. One more internet imperative that doesn't stand the test of experience.

Hey, if you want to upgrade your intake, I'm selling my 44's on ebay right now: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=270402375374&ssPageName=ADME:L:LCA:MOTORS:1123

TRUCE???? Just remember.......you started this by saying I didn't build my own engines.......Me and Five and Dime pride ourselves on building our own engines, and we do a damn good job of it! We also recognize the 1st amendment and if you don't agree with us that's fine.....but don't accuse of of not building our own engines!!!! We'll continue to try to help others on the forum with our ideas and we respect your views......OK? By the way.....great video!!!! Guy

I got the wrong impression that you didn't do your own work from this post:

Marty.....Changing the cam to a Stage III will give you about 20 h.p. Changing the cam and increasing compression to 10 to 1 will give you give or take about 30 h.p. (flywheel). To do so you need to shave and shim the head. New cams require correct rocker geometry........installation best left to a pro with access to multiple size lash pads. With parts and labor, a correct installation will cost $1,000.00 to $1,200.00 for everything! Well worth it IMO.

When I built my motor $200 was HARD to come by, and when I had a couple hundred bucks the last thing I wanted to do was spend it on parts that wouldn't make the car faster. $200 is a couple new shocks, or a camber plate and coilover sleeve for one corner of the car, or half the cost of a light flywheel.

I'm not going to push the issue any further, but you can expect that the next time someone says you HAVE TO replace the rockers, I'll probably say something about it.

Diseazd, you should seriously consider those 44s...
