ive searched a ton but am looking for any last minute tips/reccomendations before i order tomorrow. almost positive im going with the tsp224r on 114. truck is in sig, stock 3.23 gears plan on swapping to 3.73/3.90/4.10 next month. not sure which ratio yet. future plans include fast 102 and mild heads and maybe a small shot(75). eventually a 6.0 if the motor goes. please chime in with pros/cons, likes/dislikes, or reccomendations on my selection and build

 

that would be a real nice choice, and would also work very well in a 6.0

3.23 gears make me cringe though

 

I think that's a good cam choice you are looking at.

 

thats what i was hoping to hear about the cam. dont worry those gears will go away soon!

 

thanks for the help guys. anyone else?

 

I've had great results with the tsp224 114. Good choice. And with the CC, definitely go 4.10s at least.

 

that will be a good choice, i would go with a 112 lsa though because i like a choppy idle

 

i really want to pull the trigger and get the 4.10s but im a little scared. i drive my truck to illinois about 2x a yr and im worried about spinning the high rpms for long periods of time on the highway. especially in 80mph zones when i usually set the cruise at 85. thats why i was origninally thinking 3.73-3.90. half my daily driving in mixed with city so i would actually enjoy the 4.10s then i think. they would be great at the track also. its just the long trips i worry about. thoughts/opinions please?

 

You'll see a significant loss in highway gas mileage from the 3.23s, but there should be no concern about running the engine at 2000+ RPMs for extended periods of time. You gotta remember, GM sends out plenty of vehicles with 4.10s from the factory. And I know those with 4l80e's are turning well over 2000 rpms on the highway.

 

I don't see why so many folks are afraid of turning upwards of 2k rpm on highway trips. It's not like the engine cares. Hell, before the 6-spd, I'd be turning close to 2500 rpm just cruising at 80mph on the highway. And that's with 30" tires, .73 OD in the 5-spd, and 3.73 gears in back. No biggie at all..
