ok here goes

1982 transam t top fully loaded right now race weight of 3350

350 sbc with 305 HO heads,fully ported and polished with 1.94-1.50 valves.
edelbrock aluminum streetmaster singple plane intake,with 650 holley double pumper
custom grind cam, 282 duration .480 lift 106 lobe sep and 1.6 roller rockers brings lift to .500 something
hedman full length headers,into 2.5 inch dual exhaust with 2 flowmasters

TH350 trans with 2200-2600 jegs stall convertor

and either a 94-95 z28 3.42 posi disc rearend
or a 3.73 posi rearend..whichever i decide to buy before xmas..

ive heard alot of opinions on what kinda hp this should put out and what kinda numbers it will run in the 1/4 mile...but id lov eto hear your guy's opinions.

if you guys need or want any other info just lemme know..or if i forgot some info..hehe im kidna tired right now...btw ive got all this stuff just waiting to go into my car,save headers and rearend...i blew my rearend up

 

Is your stall speed a little low for that cam? Anyway High 12's would be my guess.

 

yeah i beleive it is a little low for the cam...but i really cant afford a 3k since they jump to over 200 bucks...and the stall convertor is a xmas gift..it'll have to make do till i can afford a good replacement...and so far im hearing about the same estimates from everybody

 

I'm sorry but I really don't think so. With that weight and setup I think you'll be lucky to see 13's in the 1/4. Just my opinion though.

 

I would say high 13's to low 14's. I would suggest using a dual plane manifold with the gears you plan on using and the rpm range of your engine. You might want to consider some aftermarket heads too, that would make a major improvement to your combo. 305 heads would be choking your engine even after being ported.

 

The converter and rear gear a re critical to this combination.

I would pass on the jegs converter and save for a 10" 3500 stall.
Use your stock converter till then. A stock 12" th350 converter will have a 2200 stall.
I would use a 3.73 minimum, 4.10's would be better.

Be sure to carefilly portmatch that streetmaster manifold to
your ported heads. I'ts really pointless to ask what power it will
make. Put it together and take it to the track, Then you tell us how much power it makes.

This is a very workable combination. It will need carefull attention
to detail and tuning. I'd say high 13's as discribed
and low 13's/ high 12's with the right tune.

 

well my buddy and i ran it a few weeks back on the g-tech and what came back was a 13.6@ 107..that was with the stock quadrajet intake,and stock exhaust with my 650 holley double pumper. and this was a G-TECH time..this wasnt on a race track. i dunno though...january 17th she gets put on the dyno so i guess we'll see what she lays down then...thanks for your advice and opnion guys.

 

i'd say mid to high 14's unless you really get lucky.

 

please tell me your kidding right? dude a bone stock 350 TPI transam or maro runs mid low 14s...with 240 hp. i should be so wellllllllllllllll above that. i myself personally am expecting either a very low LEGIT 13 or a high 12

maybe mid/high consistent 12s with a good tune and really good traction.

 

I have the exhaust setup for sale that you want...pm me.
