im trying to part together a 350 that will put me in the mid 12's.i already have accell intake, runners ported plenum and vette alum heads.im trying to find out if the 219 cam only works good with the superram or if it will work with ltr setup.i also wanted to know if i should upgrade the heads or just port the heads i have.also anybody with a proven ltr setup in the low to mid 12's . please show your setup thank you in advance for your reply's

 

Hmmm, I'm not sure about the 219 with LTR's, I haven't seen that combo before so I can't honestly say. LPE does make a 211/219 for LTR setups. I have heard of C4 Vettes running low 12's w/ good flowing heads, LTR's, and LPE 211/219. I would imagine an 3rd gen could run mid 12's with the same setup.

 

I'd go with the 211/219. I've seen guys on the boards going 12's with that cam. I've been doing a lot of research on cams lately b/c i need to pick one for my motor too. I've been told to try and keep the duration at or around 220*. Something about the TPI not liking anything above that. You may also want to take a look at the Comp 08-302. It's 210/220 .480/.480 (1.5 rr's) with a 112 lsa. This is what I've decided on for my car. If I have it in before you gey yours, I'll let you know how it is.

 

thanks for the info i wont have mine together till next year in the summer i guess.i put a lot of money in the crudy 305 so i should use it for a while .i just hate that i put the heads and intake parts on a 305 becuase 14.67 in the 1/4 just dosnt get it done.i guess its not to bad for a 305 .i was going to cam the 305 but i cant be bothered i figure the best the 305 will do naturally aspirated is high 13's .thats why im starting a 350 build up.well keep me posted on your car when you put it together.

 

Just saw this post on the vetteforum. The guy ran high 11's with ported TPI with asm runners and lpe 219 on a 383:

thanks for the link .i get on that site all the time for info and parts.there are a lot of quick cars on there but most of them are like you they have the superram.i guess i should have bought a super ram to begin with.but atleast that guy gave me hope:hail: 11's on a ltr:hail: i know its a 383 but i have no problem with that.if you find any more info please send it this way thanks.info like this makes me:lala::lala: :lala:

 

I went 12.45 @ 109 on Nitto's w/ a stock TPI and 305 programing.

Ok, so I cheated and used a 100shot. But I'm going w/ a LT1 intake and the CC306. 230/244 .544/.576 w/ 1.6rr. It should spin pretty high.

 

good run freebird.let me no how it runs when you change over .im trying to find proven 12 sec. ltr combos. buckeyeroc has the proven superram combo.i should have changed the subject i guess .i know the combo has to be out there and im not going to be picky like john hunkins and say it has to be emission legal .i just want to see what people can get out of the ltr .also im not bashing john.just stating it does not have to be emission legalthanks

 

well here is examples of corvette's with ltr in 12's http://forums.corvetteforum.com/zerothread?id=413713 .now where are the camaros .how much do you think these combos will slow down in a camaro?anybody please!!.there is on example of a camaro on the link it is kevin91z.he has a great running camaro but there has to be more

 

The C4's seem to be consistantly .25-.5 secs quicker than similar combo'd F-bodies. I think it mostly has to do with the weight difference.

 

BuckeyeROC, I hang out at 'vetteforum a lot. I've also noticed that the 'vette guys pull off better times than us. I attribute it to....

1. Weight

2. Better exhaust

3. Better intake in front of the throttle body

Check out Scorp's times with his engine. It's virtually the same as yours and mine.

 

What's he running now? Last I heard he made some nice dyno numbers (325 rwhp and 365 rwtq), spun a bearing, built a new shortblock, and was having some major problems with the new engine and ran a 13.1 @ 107 or something.

 

I think he's got it back together. I was very impressed with his numbers before the engine burned down. The more I see your numbers and his numbers, the more I think I have a problem with my engine.
