I was down for 11 months after spinning bearings

Spin it to 6700rpm you guys say.. .uh... hmm..maybe not.

 

Spun bearings is a oil pressure problem or something got into the motor during a cam swap and caused it.

Only problems from high RPM are when you over do the rod bolts and then you don't have to worry about the bearings cause the rod will take care of the block for you.

That's the bad thing about a stock LT1 bottom end vs. a stock LS1, at least a LS1 can drop new ARP rod bolts in there where you can't do that easily on a LT1 because you have to resize the big ends of the rods and at that point Scat I beams are a better choice.

You gotta richen that thing up some before those stock pistons have a hole in them!

who has the fastest CAM ONLY LT1 on here?

 

AFAIK, i have the fastest 6 speed.

Frank (forget user name) has the fastest cam only car overall. Its got a baby cam in it (210/224) and last i saw went 11.40s. Car is lightweight, and he gets some awesome launches.

 

That all depends. There is a guy on here with bolt ons and a cam dynoing around 267rwhp running like 12.4's. Then there are people with heavy mods dynoing 340+ rwhp who can't even break into the 12's.

 

i'm talking about quarter mile times. dyno numbers don't mean much to me. my car only put down 317 rwhp and went 11.90. and still have some more weight reduction to do .

 

i have an off the wall question. im rebuiling mine right now. i decided a wanted to go to the cc306 and spin higher rpms on a rebuilt stock bottom. im to the point of re assembling it. i have .002 oil clearance on my mains and im concerned about spinning one. im pretty sure thats fine for a street car but im not sure about all those extra revs. whats a good crank oil clearance to have on a cam like the 847 or a 306?

nice vidoes and links theres some crazy dyno #s in there.

 

.002 is perfect main bearing clearance.

Cams don't change the main bearing clearance.

yea i know lol. i just wanted to be sure it wasnt too lose or too tight for higher revs.

 

I did 350/350 on my 224/230 112 lsa on stock heads and only bolton was headers and cai....no throttle body or anything like that oh and that was with 11 degrees of false knock from a bad sensor

 

Could you post your dyno chart? I'd be really interested in the rest of the curve, etc.

 

Talking to me or untamedls1?

 

If hes talking to me unfortunetly I dont have it but I promise it was legit I have no reason to lie I just cant find where the hell it went too my peak hp was at 5950 and it held it to 6200 tq was at about 2800 I think or somewhere around there

 

I've seen yours, silly.
