Also, the distributor will need work to get enough initial timing w/o having too much mechanical timing. A stock distributor is just a starting point. Even an MSD distributor w/the black 18 degree advance bushing might not be enough. It's no big deal setting the distributor up, but it IS something that you'll definitely have to deal with before you're done.

|1Gary||I rarely post anything counter to Richard.I guess he is just answering the O/P's question.I does grade against me for any cam company to sell a cam for the "sound of it". It be begs the question what are we doing here??. Hate it.|

Where you can have the better of both worlds is to use a TH2004R or TH700R4 like mentioned already. They need help if stock to hold up well to a performance engine, but it can be easily done- for a price. Even a properly built TH350 or TH400 would be better for acceleration than the PG.
The thing is, you can cam yourself out of being able to use OD unless the rear gear ratio is very low- like 4.56 to 4.88. A 4.88 rear gear would give you a 3.42:1 ratio in OD. A 4.56 gear = 3.19, and that is about as low as you can go w/a relatively big cam w/o bringing the engine rpm down so far that OD becomes useless.

Thank you for your advice. I am going to speak about it to my friend mechanic. You helps me in my plan and, also, thanks a lot to techinspector1. I chose the 283THR7 Tumpr cam. So... with that setup, i should be satisfied. Thanks once again to all of you with your great knowledge.

Yeah the kit to replace the cable with the brain box or internal is ok. But just trying to keep the price down. I have also rebuilt them before the problem is a pro will be able to source the parts cheaper and get all the right hard parts replaced. Sun gears will break if you have too much tq if its not replaced with one piece hardened basket and splines. Not to mention the stack of good snap ring pliers you need to get the job done.
Looks like the op is all set with local tech to build him one. Just make sure he keeps the cost down for you and uses top quaility soft parts so it will last.
Also to the op i would hang onto the glide they are popular option for collector car and can always be set aside for reinstall one day. Just have it built and set it on the shelf until the time is right.

Yrs ago TCI impressed me.They are a very progressive class company.First check we received as contingency money was from them.All the rebuild parts address the issues that 700R4's have.From their monster sun gear to a number of stages in their valve bodies.They developed a valve body that eliminates the critical TV cable adjustment.So either for a you build or to buy of their trannies,it is a nationally known company with a excellent customer service department.
But we need to let the O/P post to see what direction he wants to go.

That's clear enough. Go to a 700r4. Too heavy and not strong enough for a PG.
3,300 pounds with 275R15.
Thanks to everybody for your help.

|Coolrider||I know! My mecanic friend says the same good things about the 700r4 so... I wanted to keep my fact. powerglide but... It seems that i won't have choice to set with that transmission i think. He's a transmission specialist with great knowledge in race track setup and wants to build one for me.|

Power glides are for 2300 pound race cars with a 700hp engine.
You don't have that. The glide will be a dud with 3.73's.
What is the car weight and rear tire diameter.
For a street strip motor you want to build with a 10.5:1cr (92-94 octane gas)
You are making critical errors in your combo plans.
383 with aluminum heads and flat tops and 0 or near 0 deck clearance wants a 65cc cylinder head.
you need to either gear the hell out of it or fall out of love with that glide and get a th350 or th400.

Its a good deal for a great trans he will also work with you to get it installed right with the correct linkage and lockup options.
He can do the close ratio upgrade but its not needed. The low first gear is great pulls you out the whole and second is your power gear. Usally works great with torque build. It is also only a little off not a major change like granny gear truck trans.
Also will let you run 1500 rpm on the highway. Really helps on fuel and noise on the road. Also makes your engine last a little longer if you need to drive it on the highway for any length of time.

|1Gary||If you do make a move to a 700R4 get a V8 one from the early 90's.The V8's have better clutches in them than the V6's.The one down fall of the 700R4's is the first to second shift where second is that much lower(numerically lower)you see a drop in RPM.I read somewhere a fix for that where you can get a closer ratio second.|

As far as a lumpy cam, install a CompCams Mutha Thumpr. It'll work with your 9.5:1 static compression ratio.

the th700r4 is very popular casue it works well in cars without computers. Also has low first and taller top gear. It helps alot. But it is heavier and uses more hp to turn it over. Or parastatic drag? i think its called. Not that i can spell worth a crap. and i love the powerglide but for any street car the th700r4 will make you very happy. Also with gas prices these days and trans being for sale around 1000 bucks the 700r4 will pay for its self over time. That in its self is very rare in the fast car world.
Do you have 4 valve relief pistons they may have as much as 6 cc depth and still be flat tops. if rebuilder pistons it may be even more. You did .041 as gasket height?
Normal deck is .025 and .010 is normal after being cut.
hope this helps.
