we all know it doesn't matter HOW much power you've got if it won't hook your getting your hat handed to ya by granny in her VW l

I used to give my buddy a ration everytime he showed up my LT1 sbc would plan flat leave his 350 hp 396 needless to say he wasn't real happy about it

excellent thread!:thumbsup:

 

[Southern72]

i would like to know what this 520hp 383 has in it?

If it's built like my full weight street car with with 3.73's the "stock" or "mild TQ monster don't stand a chance. A properly built 383 will have HP and TQ to mach a ZZ502 and willout ET it. A stock low compression with stock heads don't stand a chance.

 

[Tonys72SS]

I too would like to see this 383 combo.

 

[greg_moreira]

Definitely no question that a streetable 383 combo with off the shelf parts "can" make these kind of power figures nowadays, and even moreso depending on the combo. So its not a question of can it be done, but rather, is the 383 combo being discussed built with the stuff to do it.

Let us know how the races turn out. if you hook the rear meats at the starting line good, you're a likely winner. It will be interesting. Make sure you look under your opponent's hood at the track to make sure he doesn't have any Nitrous oxide surprises for you. And if you get right behind him in the tech inspection line, you'll see if he has a nitrous bottle in the trunk when they make him open it. :yes:

 

[c.chevelle]

Thanx for heads up...but i know the guy 2 well to know he aint bringin nitrous...were super close..like fam lets say..

 

[larry87]

Let us know.

I can definately relate to this topic. I recentley just posted a question about a stock mid 70's BB with pp heads that I purchased. I got some great responses from this board also. What I didn't mention in my post was that it was still in a 79 camaro that I was going to dump. Currently I am running a 383 in a 69 chevelle. It's snappy, but it's just not a big block. So for the right price I finally got my engine and a "free" camaro.

To get on with the story. I just trailored the car back to my place this weekend and decided romp on it now that the car was within towing distance in case I broke something. again: stock mid 70's truck 454 with weiand intake/headers/ 750 double pumper/ 10 bolt posi (maybe 3:55's at best), 275 tires, and a 3000 stall. I was not expecting much at all. However, Hands down this thing out torked my 383 all day long. I could not get it to hook.

The current 383 set up in the chevelle: the "real" double hump fulie heads that have been machined and ported, cam with 224/227 duration and .500 lift Edlebrock rpm performer, holly double pumper, 2000 stall, 350/w a shift kit, and 3:73's.

Don't know if it means anything because there are a million combos out there. But I will tell you that I will never underestimate the raw potential of a BB again. Good luck with the race. As someone already stated the first to hook will win!

I never ran the PP headed engine in the 1/4, but the way it was set up it would run high 11's. This is at over 3800 lbs. and over 1000ft DA.

With this same weight, better air, different intake, converter, and rear gear, shifting at 5500 rpm, it will go mid 11's.

With the 702 heads and the same changes as above it will run high 10's. L J

 

[c.chevelle]

thanxs...yea i never underestimating him..cuz ive heard BB are hellish and just with a few mods its super torquey

 

[MEJ1990TM]

Can we get a few specs on your 383? I am not doubting it, I am just curious what parts are there.

I know what I am thinking. What are you guys thinking?

1.that Caesar is trying to build a motor to beat his buddies slightly warm 454 OR 2.he is trying to decide which he should build.
3.the matchup is BS & he is just learning how to match parts for a good engine.

either way I still vote 454.

Checkout the torque curve on my mild 383 with cheapo heads. Also this pull was done with a budget 600cfm carb that has since been upgraded..

 

[cv67]

got it...no street racing...were both 18 and dnt have money..so we have moderate cars...stock suspension on both...we helped each other build our cars

Not trying to be a d%ck but....

Lets see, pay $20 and take it to fontana run with no consequence or run it on the street risk killing someone or getting your car impounded and crushed. You know thats wht they do out here right? It only takes one time and bye bye car. Dont be a squirrel...that stuff gives our hobby a bad name and encourages laws that crack down on these cars to have them taken off the road..

Get to the track and line em up theres no crystal ball to tell the outcome.
Telling ya spend a night or two out there and you wont want to streetrace again. Youll have a blast!

Dead thread resurrection? :thumbsup:

I still think that this guy is blowing wind. His 500+ hp 383 hasn't been built yet.

 

[marooned]

I know what it takes to make 550 HP with a 383 stroker motor. BTDT I would be surprised if his is making much over 350-400 HP.
My opinion could change with some better info on parts in the build.
