hey guys i just installed a l05 i rebuilt just wondering what you guys think it will run

rebuilt stock l05 9.3 compression

ported 193 heads (ported as per dynodons guidlines) 3 angle valve job and back cut valves
lt1 cam (202/208) and valve train with new pushrods and comp 981 springs
edelbrock performer intake
holley 750VS carb
headman headers and flowmaster catback
sphone sfc's
rebuilt 700r4 with 2200 stall
ls1 aluminum driveshaft
factory 3.73 gears with auburn posi

so what are they guesses as for 1/4 mile i did some searching but most people with this engine are tbi while im carburated

im hoping for low 14's to mid 13's what do you think

mid to low 14's i'd say. somewhere around 94mph...

do you think a slightly larger cam would get me into the 13's

mw66nova

iTrader: (13)

that cam will get you there with better heads. shoot, just some 416 or 081 heads or something along those lines would work. and go to a double pumper carb. a properly tuned double pumper will do far better performance and streetability than a vacuum secondary. if you want to go fast, you need a double pumper.

you really think those heads will hold me back that much they are ported and the numbers dyno don got out of his 193 with just minor clenaup were rather inpressive i believe it was 224intake and 215 exhaust but i did plan on keeping my eye out for some vortec/afr heads

i say run it like it is. this will give you a great base line and help you learn how to tune the car. if anything, i'd really like to see you upgrade to a double pumper before anything else. then after you learn what the car likes and are really comfortable with it, start putting on better heads and cam and whatnot. vortecs and a better cam (something with 230*-240* duration at .050) would put thing well into the 12 second range with a better intake and a double pumper.

well if anyone would know i would be you i have watched you squeeze every ounce of speed out that 305 you had and our cars look really similar mine is white as well but i have 16 inch irocs but painted black... im hoping i can get the chassis dialed in with this setup to (its lowerd about 1.5 inches all the way around)

I had almost the same combo in a 5,500 lbs van, stock 3.08 gears, 2,000 rpm converter, 700r4, STOCK TBI and STOCK TBI intake, lots of chip tuning. It ran a 15.6 @ 87.6 with a 2.55s 60' into a 20 MPH headwind.

what do you think that be in a thirdgen??

mw66nova

iTrader: (13)

just by taking 2,000 lbs off using the 100lbs is worth .1 second, then it equates to a 13.6...but that seems a bit optimistic honestly.

Well, Lo-tec posted the following about his swirl port equiped 350.

My old 350 (used wrist pin knocking warranty motor out of a 90 cadillac fleetwood brougham) went 13.61@101.5 with a 1.91 60' with minimal mods. This used 40K motor had a crane TPI cam (.452/.465 with 214/220 on a 112, 3 deg. advanced) and normal bolt-ons (cheap shorty headers, performer intake, exhaust) and 3.73's. Stock 700r4 and stock stall from an 88 GTA. This motor had the crappy swirl port heads and ran awesome for an "el cheapo" special.

His heads will flow better with porting.

well then, i may just be proven wrong on this, and i hope so! interested to see how the car runs/acts.

ill be sure to let you guys know im just ironing out the kinks now becuase i changed engine, transmission and dual fans and converted to serpentine belt all over the winter so just trying to get it all set right
the holley i just put on seems to be running rich at idle and loading up the plugs i think its cause the person i bought it from thought it would be cool to paint the carb which is ok but NOT DOWN THE VENTURI !!!! so i think the idle air bleeds are a little plugged up so gotta straighten that out first

went to tune the car a little today and it has developed a deads skip so went around with my timing light and found a cylinder with intermittent spark changed the plug and nothing im still thinking it may be ignition but im a little concerned. I dont have any other noises (ie knocking) oil pressure is a steady 50psi at idle what could cause the timing light to intermittently light on that cylinder?? it was fine all the others, i dont think a loss of compression sould casue an IGNITION misfire should it?? it could cause a misfire but the plug would still fire hmmmm
well i think i will bring home a compression tester tomorrow just to check it out
i do have a jegs ignition module in there so maybe ill put the stock one back in
aaarggggggggggghhhhhhhhhhhh!!!!!!!!!!!!!!!!
hmm maybe valve adjustment???

mw66nova

iTrader: (13)

make sure it's not the plug wire. keep it simple.

and my timing light is intermittent...but the light has been around the block and you have to hold your mouth just right to get it to work...it's a piece.

tried the plug and the wire no go i do have a summit brand ignition module so it might be crap i have my old gm one sitting ready to go in

just bouncing some idea's off you guys

i see only one possibility for the miss

ignition (cap wires module etc)

because head gasket would give me other signs like coolent in oil, overheating or two dead cylinders (leaking from one to the other)

plus any loss of compression would result in a loss of vacuum as well wouldn't it??? im still solid at 21" at 800 rpm not really flucuating that i can remember

heads are just redone seals valves comp springs etc

grrrrrrrrr now i gotta wait all through work till i can figure this out .......its gonnna drive me nuts
