Cam selection
Hey gang,I’m new to the late medel corvette world.Finally graduated from mustangland.I recently sold my 01 saleen and purchased a low mile 99 coupe.I am starting mods on it and noticed the balancer issue already.I was planning on doing a cam and converter alittle later but if I’m pulling rack and balancer why not get it done now.I was checking cam specs,and was wanted to know if anyone had any experience with the 228R cam from Texas speed.It is 600 lift int and exh.228 both and 110lsa.Im staying N/A ,doing long tubes and likely a 3500 rpm or so converter.Thanks for any input.

It's a universe of information out there. I recommend to do as much research as possible. For me it was actually part of the fun, the learning and research part. Of what I've read and heard from experts, there seems to be a common theme of having more duration on exhaust than intake due to CFM differences between intake and exhaust. I think you'll benefit more with more exhaust duration if you're looking to increase your NA gains, IMO. 230 or more is what I would go for. I have a 228/230, and if I was to do it again I might've gone with even more exhaust duration like 232-234.

I've got some details here on a pretty basic build (well it started that way, out of control now).
I am in the process of adding a Fast 102 ported by Mamo and will make a new thread on that within a month for those that like to see a car progress.
Happy modding! TSP can always guide you through a build. There are other companies out there as well that do great work as well.

What is the differential gear ratio? 2.73 or 3.15? A 3500 stall converter may not have the street manners you are looking for. My old 99 coupe I ran a set of TEA 243 heads, 232/236 .595-.601 cam, 2800 stall, 3.42 gears, long tubes, ported intake. It made 430 at the wheels and was very “streetable”. My 02 convertible I am running a Magnacharger, mild blower cam, long tube headers exhaust, stock stall and stock 3.15 gears. It makes 480 at the wheels with a conservative tune and 5 lbs of boost. I have about the same amount of $$ in both setups. The vert is the better set-up for daily driving and weekend fun.

We've done a few builds with this cam. With heads we've made north of 415rwhp with an auto/2800 stall. One customer was recently telling us they run consistent 11.5s.
