Default AI 200cc package

I'm rebuilding my engine and am probably going to go with this heads and cam package on my 95 6 speed TA. When I talked to them they recommended a 22X 230X cam with around .580 lift. What I 'm wondering is how driveable this cam is. I don't daily drive the car, but I do drive it to work on nice days and make some long trips in it. I can end up stuck in traffic and want something that will behave in stop and go traffic. I'm also concerned a bit about longevity, I don't want to be changing valve springs every 10,000 miles.

Anyone running this setup on the street and putting lot's of miles on it?

That cam would be just fine and very drivable as long as you have proper tuning. Unless the cam is like ridiculously large poor drivability is usually more of a tuning problem than a result of the cam selection.

I run a similar heads/cam package by Speed Inc. Maybe a tad bigger than your cam. I don't daily drive my car but I'm sure you can have it tuned to be driven with better streetability.

That cam will be plenty driveable. I have about 5-6k miles on my heads/cam. The last 1k is about 1/8mile at a time (lol). The valve springs they use and cam lobes will last a long time.

They engineer the valvetrain to outlast the combo so you should be fine. They told me they had no problems with people running them for 40-50k miles and if my shortblock survives that long I'll be happy.

Depends on what gear you run with. That combo will require a tall gear and the engine will get heat soaked on the e-way for extended periods of time. But if its only once in awhile that you plan driving e-way speeds for long periods, you should be fine.

So... you are saying this combo, with a 22x/23x cam, will get "heat soaked" more so than a mild combo and shouldn't get "heat soaked" but maybe once in awhile? Why not explain yourself in greater detail. I don't believe the more challenged members like myself really fully understand where you are coming from...

A six speed LT1 with 4.10s in 6th gear will spin about 2k at 75mph . How is that going to heat soak your aluminum heads any more than if you ran a smaller cam.

With a full build you will be easily able to get compression right which goes a long ways towards helping drivability. That cam will be fine.

I have 2 year and about 16K miles on my AI combo and all is holding together well, and mine is a lesser package than they sell now. They do not offer the heads or springs I am using.

I run a similar Joe Overton grind, 226/234 .568" on a 111 lsa and its extremely streetable...Hell mine could be a DD if I didn't have the Subaru to take to work...These motors love smaller durations with bigger lifts...

Hey man,
Awsome choice on going with AI for your deal. I called them about a month ago and thats who I've given the nod to for my work. I am realy curious as to how it will work out so keep me posted or send me your email adress so I can keep track of your progress. I have a questions, on your shiping cost, I live in north western canada(you take the ferry to alaska from where I live) and I wonder how you are shiping and how much it will cost to do it.
Also, 22x 230x cams? They told me that with out getting totaly into details that maybe a 306 would be beter? Who makes the 22 and 230 and why do they think there beter? Also I'm not trying to be rude at all here, does WA for your state mean Washington? I live in British Columbia, that's north of you. Just try and figure out shiping.

Yes, I'm in washington state. I don't know what shipping costs will be as I bought a set of e-bay heads that are in Florida and am having them shipped directly to AI. I don't know who grinds the cam, but from the research I have done I have decided to go with a billet core cam instead of cast and I think it would be hard to beat a heads and cam package that are meant to compliment each other. Also I will be having my machinist follow AIs recommendations as far as pistons and deck height to end up with the proper compression and quench to run with the package.

I will post up progress once I get the motor out and actually get started on the work.

I went with a bigger custom cam with my 200cc AI package and its very streetable (its in my DD) Trust Ron and Phil they will deliver what you ask for.
