86 Monte Carlo Street/Strip Car

That's a pretty tall order - I can tell you it will take 650 Hp to run 10 flat.

Here is an article on my friends car you might find interesting.

Curt Connors’ 9 second carbureted LS1 Monte Carlo
March 5th, 2013

Curt Connors and his family are well known around the Mid Michigan Motorplex. They are die- hard bracket racers that make the weekend a family event. Curt’s wife Melissa and his parents all spend the weekends at the track most of the summer.

Curt’s 84 Monte Carlo is back halved, with a Mild Steel Cage. The Dana 60 houses 4.56 gears spinning 14×32 Goodyears. The car is all steel except for the hood and decklid, with stock glass throughout, but Curt has managed to get the weight down around 2700lbs. Just right for the Transmission Specialties Powerglide and 8” race converter to do their jobs.

The engine combo is a straightforward setup. It is 403 CID, based on a 6.0L LS1 truck engine. The stroker kit consists of 4” stroke Callies Compstar crank and 6.125 rods, and Autotec flat top pistons. Final compression ratio is a hair over 13 to 1. The heads are CNC Ported RHS units from Competition Components, with 230CC Intake runners, 2.080/1.600 stainless valves, and optional solid roller springs. The cam is a custom solid roller, with 260ish duration, and .750 lift. Lunati roller lifters and Trend heavy wall 5/16 pushrods make sure all of the cam’s lift gets to the T&D 1.7 ratio rockers. The engine is topped off with a hand ported Edelbrock Super Victor intake and a Holley 950 gas carb. The stock LS coil packs are run by an MSD timing controller. Headers are modified Schoenfeld Circle track headers, that were coated at QC Coatings in Utica, MI.

Curt’s first time out with the new combo was at the final test and tune day in 2012. Baseline passes were in the 9.80’s @ almost 138MPH. There wasn’t any time for any real tuning, just a few shakedown runs. For those first few hits, Launch was 5200RPM, and shift points were 6700. For next season, Curt has a new converter from Lenny at Ultimate Converters in the works, as well as some other refinements in the works. We are as excited as Curt to really put this combo to the test during the 2013 season. Stay tuned for more results!

A 6.0 should easily make enough power to go 9's with a 80mm turbo. What will the compression be with those 5.3 heads? I think your biggest obstacle will be trying to hook with all that power you'll be making, I think you're gonna have to mini tub to fit a 325/50/15 DR under there.

Thanks! Had my house windows shaking

the turbo route is in the right direction for making "streetable " HP. have you checked out the X-275 car class ? I know that these are very high HP cars , but the frame / tire to hook up is very close to what you might expect.i had a 79 monte street/ bracket for about a 10 year span , as the drive train went up in power( last set up 408 cu in -220 afr headed / 2 stage NOS ) I notched my frame rails /narrowed the rear end and ended up with mmmm, cant remember final tire size, but you get the point. and yes I still drove it on the street some times.

You must put a cage in it if you go to the track, they will shut you down so quick your head will spin. That's if you get to you goal. I would go with the turbo set up you well have more street manner if you stay out of boost. Still a tall order for a street car tho

Saw a guy from town run several 12:70 passes without a bar. I asked him if he was using the NOS and he said yes, I knew it was bull. I watched every run and they were pretty much the same.
When almost everyone had left and the sun was starting to go down they announced there would be one more run. I watched him run a 10:80, collect his slip, and drive right out the gate.

Later when I asked him about it he said when they handed him the slip they also said they would like to speak to him in the tower :lol:
That was in the early 90's and up till then I'd never been a believer in NOS. I still haven't used it.

Yeah, that around the time mine broke in the 11's they told my father that he had to put a cage, 5 point safty belts, helmet And no more passengers were allowed to go down the track. Lol
