how close do you think this setup would be to a 97 LT1?

350 with 041 heads, crane 278-2 cam, performer intake, and headers?

 

What type of induction will this 350 have?

 

How close? I suppose you could set them together, touching. You can't get much closer than that.

As far as a comparison, the L98 will have a heavier crank, rods, and pistons, poorer balance in the rotating assembly, an inferior control system (even with the MAF), poorer head flow, heavier valve train, and if my information is correct, you'll be using a flat tappet, solid lifter cam (278 grind), which might not be a big penalty at higher RPM, but if used with a TPI could be a complete mismatch for the induction system. Even the milder cammed LT1s available in the '97 model year will out=pull the 278 grind, then the LT1 intake will out-horsepower the L98 induction. Couple that with teh noise created by the valve train and subsequent spark retardation from the EST after the detonation sensor goes wild, and you will really suffer at all ranges with the '87.


Other than that, it's pretty close - if the two blocks are actually touching. You weren't planning a race, were you?

 

OOPS! I overlooked the part about the "Performer intake", which probably also implies "Carburetor". That will only cost you a little low-end torque, but will make up a little at higher RPM. So you'd be even a little farther behind from the start, but would tend not to lose ground as fast once the wheels start turning faster. You'd only be fighting the heads at that point. And for the fuel mileage, you'll lose at all RPMs.

 

Could also mean TBI as well (performer TBI intake). We know how much of a non-threat us TBI'ers are

 

well, i guess i'l stick with my 455 in my '80 TA if its going to be that bad. i know that will smoke the hell out of an LT1 once i do a little work to it.

BTW, it dosn't have any electronics so it will have no knock sensor or anything. its also not an L98, the heads are much better according to chevy hi performance, 462s which i understand are about the same as 041s flow about 20cfm more at about .500 lift and about the same at lower lift(can't remeber exactly, but i know they flow a lot better than the L98 heads). i also would be using the hydrolic version of the 278-2 and the rotating assembly would be ballanced.

it would have a 600cfm carb at first then i would put a 750 on when i could get one.

 

I'm not sure what your data is, but '462 heads (stock castings) don't flow as well as even the iron LT1 heads, nor even as well as the L29 or L31 Vortec castings. If you're talking about ported heads, that opens the door completely, but it opens the door even farther for the later heads. It's about time we all faced the facts that the admired, old "Camel Hump" or "Double Hump" casting mark heads really weren't all that great. They were a lot better than the other stock heads available in their day, but the 30+ year old technology doesn't hold a candle to the stock heads developed with that 30+ years of experience.

And that doesn't even begin to touch on the fact that the '462s are typically 62-64cc, while the LT1s are 54cc with a more desireable kidney shape.

I thought from your original post that you were talking about a stock, '87 model year 350 V-8. Apparently, I shouldn't have assumed that - That'll teach me.

 

l98's aren't that bad.

Buddy of mine runs a pretty much stock l98 (free mods, hooker headers/catback and thats it). Stock 9 bolt rear-end.

Runs 8.7 in the 1/8th.

For whatever reason he does really really well at the track. A lot of LS1 cars aren't breaking out of the 9's for some reason. And buddy of mines stock 96 formula only runs 9.4's...

Anything is possible.

 

I'd havta say those LS1 drivers need to learn to drive a lil better.. though I never ran mine in a 1/8 just a quarter.. 13 .1 my first (and only run with it, its quick for a daily driver but it can't hold a candle to my RS) in bone stock form from the factory.. as far as an l98 pulling a good 1/8 time it makes sense with good traction and the fact that a tpi system is all low end torque.. if your only going an 1/8 of a mile because you wouldn't be too far into top end:

 

me too.. it said 87 350 with a cam and different heads, I was thinking solid lifter l98 which didnt make much sense to me as a good match.. it could have a chance against a bone stock lt1 though with the right gears, traction, good tune etc.. My friends 97 z was only capable of low 14's high 13's in stock form..
