68 RS SS convert test drive 383 stroker SBC engine/Partriot Performance

First run after couple hundred miles of break and dial in on the engine, 700R4 trans, 373/posi and (leaf spring/sway bar) suspension. Rolling Start (to get around corner) 5mph-100mph sub 9 seconds seems too fast for the weight and HP rating from Patriot at 450hp. The car does feel more like 500hp, and the 0-100mph number seems fast for even 500hp in a 3000lbs car. I'll re-try this again with a GPS system to get the real numbers from a dead stop but for now its fast as $h&*#t for a convertible.

very nice

[@sfraserusa]

Yes Happy. Only issue is that I was expecting 450hp and have +475 - I can live with that :). I bought it through Summit and had a ton of questions that Patriot's support team answered for me along the way. They also ended up getting me a Quickfuel that was setup for this engine and was much better than the Holley I was trying to run.

Dang dude that's nice for sure,I wanted to put a 383 stroker in my 03 Silverado with 450 HP plus my truck is a 5spd Manual so it would be even more better Lol

[@SugaDaisy]

Sounds fn amazing! What torque converter were you running??

[@Sinister_Reaper]

lol id love to have that and put in the 9800 rpm camshaft and 1.65 rocker arms i found for sale

[@demarques1911]

torque is what u felt.... thats what made u move... esp from a 383... i have a 383 that has 522 ft tq... and thats what u want...

[@sfraserusa]

Dat Right D Truck! This engine was rated at 450ft lbs/450hp, felt like + 485ft lbs. in a 3,300lb car.

[@demarques1911]

how much did u pay for that engine? i love it

[@shannonlane5647]

I know this is an old video but its still sweet....what stall is that?

[@sfraserusa]

Hi Shannon, thanks! It was stock'ish - 2200 or 2300 in a BowtieTransmission's 700R4 stage3. Cam (i dont remember specs) was not that big/revvy more low hit on torque, so it worked well. Bigger cam, prob get smaller one..

[@shannonlane5647]

@@sfraserusa Thanks for the reply....mine is in a Chevelle so about the same weight actually maybe 100-200 lbs difference....I also have a 383...cam is high .500's lift on intake and exhaust. Never had it dynoed but its most likely around same HP as yours est. 450-500. I have a built turbo 400 which is a good trans but I want OD and I want the kickdown/detent like yours as its just a street car. Love the way yours runs, barks second and has OD. Awesome car.

[@demarques1911]

still have it?

[@sfraserusa]

I wish. Sold it couple years ago to a collector. He drove it one, spun it out and parked it :)
