1st time 347 Stroker owner

[Jgruggs]

--------------------------------------------------------------------------------

Just got a 347 in a 92 coup and need some advice on some things. It has a 150 shot plumbed up and has been run before....car has set for several months. I need new plugs...what kind/how hot? I am making the car street legal, so I changed out the 3in straight pipes with turndowns , virtually no mufflers...awefully loud, but what a sound! Changed to 3in with magnaflow free flowing exhaust out the rear. Put a new set of Nittos out back, the slicks just aren't street friendly. Gonna add some gauges...oil press., water temp, fuel press....car has oil press gauge, but I don't like the look or location, any ideas where I can install and what type? Any other gauges I might need? They were purging the N2 thru the motor?? I am adding a purge system from Harris Speed Works and a few other items. Any tips for a new stroker owner? Previous owner said it ran 1040's on the gas...outta be a blast. I am going to a tuner soon as I install all gauges and purge system , just wanted to change plugs before I took it in. Also, 1 small problem, I believe the injectors are leaking down after I kill it...it will not start after running for several minutes untill you let it sit for an hour or so. Then fires right up and purrs. Don't know what size injectors are in at this time, what size would I need if I decide to change em out? Thanks for any and all advice.

Nitto's will not be enough. There are other DR's you mite wanna get instead, and have street friendly manners. They sell clusters for the gauges. Just depends on where you want them. A lot of guys take out the vents above the radio and put 3 of them there. I'm assuming you have an after market tach?
The tuner should be able to tell you what size injectors you have.

Can you see what color the injectors are? My 60#'ers are all black. My 36#'ers are blue. I believe my stock 19#'ers were orange. Don't know what 42#'ers are.

Nittos won't hold? Cool! I've got em already so just have to wait untill they are wasted then try some BFG'S maybe. See I don't know what to expect outta this thing, can't wait to get it on the road. Yeah I want some type of cluster and in the vent area might be the ticket. I want something clean and functional. It has a c-4 with a 3 speed lock out reverse and transbrake. Yeah it has a big ol tach and shift lite. I'm at work right now and can't look at the color of injectors....will later and compare with the colors you listed. Thanks fellas for replying
