Hey guys, I have an 86 T/A with a 4bolt vortec 350 w/ the SDPC vortec TPI manifold, 1.6 RR's, .480 lift intake and exhaust. adj. fuel pressure regulator, 24lbs accel injectors, 1 5/8" edelbrock TES headers and SLP siamesed runners. Does anyone with a similar set up run against the LS1 camaros and T/A's, and ow did you do? Did you hang up with them or did u get walked or just flat out blown away? Keep in mind the Heads I have are stock vortec heads with the exception of the machining of the valve guides for the .480 lift. Im probably going to be running against someone I know with a 2002 Ls1 Z28.

Thanks,

 

i think it should be a pretty close race.

the ls1 may have you by just a car length or 2 though.

just my 2 cents.

 

Ill give it to the ls1, if it has any mods at all.

 

Thanks for the response guys, Ive talked to some guys that have the same manifold set up and some say they can take some Ls1's and they had a smaller lift cam and less modifications than my set up. Guess it also depends on the driver. Im curious as to horse power ratings though. I compared my set up to the SDPC set up on their 1992 z28 L98 350. They had an Lt4 hot cam, 1.6RR's, high flow runners, 1 7/8 headers and a 58mm throttle body. The car made 356 hp and 285 hp at the wheels. My set up is almost the same except for the cam and the headers and throttlebody. I thought maybe I would be in the range of about or around 330 to 340 hp. Would this be way off or semi accurate?

 

i would say semi accurate.....

The hot cam is a little bigger i beleive. The headers are also going to add a little on the top end too....

I think it should be close..... Drivers race imo most likely.

Racem and tell me how it go's

 

I will maybe this summer. Im finishing up the car soon, just waiting for the weather to get warmer and then a little more work here and there and i should get this thing fired up.

 

should be a hell of a nice car.

I'm awaiting dropping a mild 305 in place of my 170hp monster.

Should be nice to see 275-300hp in it. Doubeling your hp while upping overall efficiency and possibly gaining gas milage is never a bad thing. + who knows theres the possibility that i can race a civic now without having to worry about a v-tec lol....

 

Thanks flaming, good luck w/ your mild 305. Im thinking if i get a 2800 stall speed w/ the set of 327 gears i have now it should be a pretty good torquer off the line.

 

yah should definetly kill the stocks off line performance by a good bit hehe.

I appreciate the luck btw, will probably need it being my first engi9ne swap.
