Don't forget I said 4400 w/ driver
add fuel and a spare and whatever you have under/behind the seat

my 82 short bed stepside 2wd weighed 4400 with me in it last time I went across the scales
of course both tanks were full......

Sux, Last trip to the track I went 12.40's @ 109mph in street trim. A little lighter now & moved some weight to the rear (fuel tank) to help with traction. Hope to be holding an high 11 before summer is over. Built out of parts most guys going racing would throw away. Lorne

^ That's awesome, Lorne. It seems hard NOT to run 12's in pretty much anything that uses an Olds, or even a Buick or Pontiac 455. The power that can be unleashed from those things is crazy. I imagine you had to make custom motor mounts to get that in there? What about the tranny?

well to give you an idea i ran my truck at MMP and i got a 15.20 @92.
at my local 1/8 mile i got a 9.90 @ 74.
my setup is nice but still needs work.
and mine is a long bed truck.

and i still got a stock 10 bolt 2.73.
60 fts were ok like 2.2's

and like haulin it said that cam is too much for a low comp motor.
needs to be around 9.5 or so.

Sux, I'll send you a PM a little later, I don't want to get too far off of T-5's original topic on his post. Anyone else with questions, feel free to ask. Lorne

Capt. I can. I just wasn't sure there was much interest in what I'm up to (Olds engine, drag race, ect.) Is the Member's Ride's section where you would like it? The truck, like many is really a on-going group of projects, so I wasn't sure. Lorne

I RAN 14.5 THIS WEEKEND WITH A 350 HO CRATE WITH 330HP AND A 3.73 IN THE REAR, I ONLY HAD ONE PASS ON THE TRACK AND THINK MY TIME COULD OF BEEN BETTER WITH MORE ATTEMPS.

I'm betting the line was too long for you to run again...right?  I heard that the wait time is like 1hour sometimes down there at HRP.  But everybody says it's worth it because that track is prepped real good.

T5, some drag radials will definetely help your cause, your 60 fts are killing you. anything you gain in your 60's will double in your ET. I don't see any 13 sec timeslips in your near future unless you do some upgrading however, but some low 15/high 14's are definetely in reach. you won't need 450 rwhp to get 13's but you will need 400+ flywheel hp to. I was running 13.7 w/ a 425 hp 454 ( guessing on hp ) and 1.9x 60 fts. I ran some 275/50/15 MT ET radials  (26/10.5/15) and they would dead hook my current 496. 3.42 gears are a good street/strip gear and 3.73-4.11 are a good strip/street gear. until i put my 496 in I was lucky enough to have OD so I could run 3.73s and 27" tires and still knock down decent mileage while running 13's. Patriot makes some excellent budget SBC heads worth looking into to raise your CR and up your flow. Keep racing and enjoy watching those numbers drop!

Ps- my all steel 85 w/ iron headed BBC weighs 1990 KG ( 4378 lbs ) w/ me in it and one tank 1/2 full.

Thanks for all the help. I decided to go with an auburn gear limited slip instead of the old gov-loc after hearing some horror stories. I also installed a 3.73 gear set from richmond and some 275/60/15 hoosier drag radials to run in, and boy do i love it, gas doesn't tho lol. I took it to the strip this past sunday to try it out and my best run was a...
13.953 in the 1/4 @ 98.67mph
8.957 in the 1/8
2.020 @ 60'
Motor wise the only thing that i changed was a new 650 holley carb and a k&n air filter. Again, thanks for the help. This website has been a great resource.

congrats t5, you're hooked now buddy ;). if you haven't already and you have the shorkel type air cleaner, you can cut the rain guard of the air intake beside the rad and you then have a 3+" ram air system. you can carry a spare non-cut one with you behind the seat in case it rains. :)

^ Hey 85shorty, I see you are a fellow BC dude too. I'm down in Chilliwack and also have an 85 shorty 2wd. I checked out your cardomain page. Pretty nice ride, and quick too! So you rebuilt the 496 and 40 min. after it was done you took out a piston? Or did I read what wrong? I didn't even know Chetwynd had a drag strip. I thought Mission and Ashcroft was it for the province. What does your buddy Dean's truck have in it to run 14s? A 350 I read, but what kind of mods?
