Okay, got my head flow numbers today and the cam manufacturer suggested I go with a 230/236 with a 110 lsa. My question is......how will the 110 lsa be different from the 113-114 lsa? Originally I was going to go with the 114 lsa on the 230/236 cam. Need to be able to drive this car without worrying about stalling. I need some advised on the 110 lsa....please chime in cam guys...looking for the 380-400 rwhp but also want the car drivable on street.

 

Idle is going to be rough. Very loppy compared to the 113-114.

 

Doesnt the LSA affect things such as brakes and ac because of vacuum?

I was running a 226-234@50 with a 110l/s and I loved it. Ran awesome. My new cam is 230-240@50 on a 110l/s but haven't cranked it yet so don't know how it's going to drive but I know of a few cars with much bigger and cruise well. It's in the PCM tuning. Later Clint

 

I wouldn't recommend a 110 for a daily driver. You'll probably regret it. stick with 112.

 

Ditto. If you get it tuned right, you will be fine.

 

110 isn't that radical. I think you'll be fine with a good tune, as mentioned. You might also want to discuss your goals & flow #'s with some other shops that custom grind cams. You'll probably wind up with something very driveable with both more power and more useable power.

 

more usable power going with the 110 over a 112 lsa?

 

Sorry, by saying 110 isn't that radical, I meant that in the grand scheme of things. I can't speak to the design of the 230/236 on a 110. I don't know much of anything about actually designing cams, hardly anyone on this site does (there are a few though). I know enough to generally understand some of the significance of the numbers I'm looking at, but that's it. There are folks who've spent years researching and learning about this stuff. I gladly defer.

As mentioned earlier, I think you should consider some shops that design cams. An internet forum is well and good, but at the end of the day, it's your car and your $. Seek the advice of those who do this for a living. Off the top of my head, I'd call Bauer Racing up in Buffalo (I think) NY. Do a search on the name 'sstrokerace'. He'll get you going on the right track, those two (him and oldsstroker) frequently dispense great info on this stuff - and they do it for a living.

 

Well, SStrokerAce isn't in Buffalo...too much snow! We're about 3 hours away where I drive my Vette about 10-1/2 months of the year.

Bret's in the business, I'm just a consultant. (That's an Old Fart with some education and experience who thinks he knows it all....)

I agree that you should get professional advice if you want a cam well suited to your application. There are a number of folks who do this for a living. Generally they will recommend a complete valvetrain package with parts that work well together.

My advice: don't get hung up on LSA numbers. They are a effect of getting the valve events where they need to be, not the cause of the events.

 

Ah, sorry about the misconceptions there on your location & business..

 

Hey, I don't know VA from West VA, so we're even.

Some folks in NY think of us a 2 states: there's New York City area, aka, "The City", where half of the people live in a couple % of the land area, and all of the rest of us who live "Upstate".

I have a precision parts manufacturing business, so there is some crossover engine work with Bret.

 

going with the 112lsa on the 230/236

 

Interesting to see cars that hold crap vaccum stop quickly?

More of a weekend warrior car, why stop @ 110 with a M6? Daily driver, keep it more tame, at most 112.
