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.

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.|

|Coolrider||I own a 67 Beaumont that you can see, i think, with a clic on my coolrider nickname.|

|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.

street/strip and power glide?what car?
I converted my 67 Camaro back in the day. It had a solid roller cam,5.57 gears. It could not be driven on the highway at all.It had a top speed of 115 mph.
I also used a 5,000 rpm stall.
before that it had 5.13 gears and a 4 speed.
that was in the late 70s.
With todays technology you can go faster and have a smother idle. I would use an O/drive auto and maybe as high as 4.30 gears depending on engine and car weight

|Coolrider||It will be with flat top pistons and near zero deck. Honnestly, the compression ratio calculator says around 9.4:1. That's what i'm looking for something like a race track setup and great torques for acceleration.|

|1Gary||Yepper.I think builds could start from the rear end forward to have a matched build.You kind of stuck between a rock and a hard place having a limited RPM engine and a two speed trans and the 3.73'srear end gears.Honestly when I saw you using a glide I almost suggested a brake for it,but what's the point when your engine can't spin up to make use of it.|

Powerglide and cam combo (Street-strip)
Hi! And... excuses my poor english speaking usually in french so...
I'm looking to build a 383 with the biggest torque gain having a powerglide (with TCI kit and 2500 stall) that i wanna keep. I did a lot of searches on the forums and... Oh!!! Not easy to be fixed. I stopped it at the following cam:
Basic Operating RPM Range: 2,000-5,800
Duration at 050 inch Lift: 225 int./225 exh
Advertised Duration: 278 int./278 exh.
Valve Lift with Factory Rocker Arm Ratio: 0.525 int./0.525 exh.
Lobe Separation (degrees): 110 (Not less, having power brake)
My rear end ratio: 3.73 and my intention is to get strong acceleration. Also, i like choppy idle and have tought about this one: Howards Cams Retrofit Hydraulic Roller Camshafts 110525-10 - SummitRacing.com
I plan to get the 75cc AFR 195 (It should give a 9.5:1) I have the Brodix HP1intake (0-6000 range and would be good for torque?)
So, what cam and carb suggested?
Thanks a lot!!!
