116 lsa question? On a 222-228 dur. Comp cam with x-er lobes.
Will this get rid of or decrease significantly missfire codes,tb drilling,surging etc.
Everyone seems to be going 110-112 range for the sound.
I could care less about the sound i'd rather sneak up <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> .
I realize it will move up the power-band but would be willing to make the sacrifice for better driveability.
To sum up,will it make that much of a difference or would i be wasting my time?

Re: 116 lsa question? Your idle should be great. This is a XE-R cam? If so you will be fine.. You will need tuning.. No getting around it.. So many people want to skimp on the tuning.. I can understand if you live a long way from a tuner..

Re: 116 lsa question? The 116 LSA will not move up the power band --- it will widen it. Peak HP will be slightly lower, and at a slightly lower RPM, . However, it won't fall off as quickly after peak.
I know this is still a controversial subject, after zillions of posts. That's my opinion, & I'm sticking to it.

Re: 116 lsa question? I had a GTP 232/232//116 a few years ago and it idled extremely well it sounded like a B1.
I'd for sure go +4.
Also consider 115 as well that stuff idles great.

Re: 116 lsa question? I wouldn't go too high on LSA with the XE-R lobes personally. You will likely see a hit in the 6000+ range as you will be reducing the overlap area. You will also see some hit in the mid-range unless you advance the cam. Advance will also hit the high end power. I'd recommend staying in the 221-222 range on duration and run a 112 or 114 LSA.

Re: 116 lsa question? I read in a Hod Rod article that a Mallett car had a cam with 229/229 with .600" with 119 LDA. It was used on a 434cid with a Vortech SC and put 680HP to the wheels and 27.5mpg
Re: 116 lsa question? Should idle close to a Z06. The cam that they have in thoes is on a 116. Id say go for it. If you go for the 115 consider the slp cam. Let us know how everything goes.
Re: 116 lsa question? You'll increase idle vaccum by about 1"of Hg over a 114 or 2" of Hg over a 112, and favor the higher rpm. Build it out of a XE-R in the 224 range and you'll have a nice sleeper, or you could go with a 114 LSA cam and be pretty close.
I will not play with the power too much, it will flatten it out some and favor the high end. It's not the overlap that makes it work up top ( a 224/224 with 116 will have negative overlap @.050"lift) it's the intake closing point it closes the intake valve later.

Re: 116 lsa question? Negative overlap? I don't get it. You either have overlap or you don't. Wouldn't negative overlap basically mean that your intake valve was still open when the exhaust valve started to move?
