I'm looking into buying a new GM Goodwrench motor to replace my 88 L98 TPI, that will both pass strict emissions and be 100% compatible with my current TPI intake system. I'm interested in the 350 HO, 330 HP model with the Vortec heads, but it says it is for 73 and earlier vehicles not requiring emmisions. I DO NOT want carb, and I am 100% keeping the TPI setup and all emissions. This car will want to run on 87 octane as well. I'm not wanting like a 400 HP + motor, just a hassle-free, durable TPI compatible 350 crate motor in the 270 - 350 HP range that will meet emissions and run on 87 octane.

 

I havent seen a V8 with over 200 HP that doesnt need premium fuel. Why put that 87 crap in?

Premium fuel over 200 HP? Nah I run 87 all the time and havent found 89, 91 ,93 ,94 any better. Plus I ran quicker in the ¼ with 87

is there any differnece in octane besides the price? i heard that if you have compression higher than 10 or so, then you need the higher octane.

Higher octane is used for high compression. Preignition.

 

you havent? ive seen plenty. as for 87 'crap', are you one of those people that will put 93 octane in a car that even tells you that it requires 87? would you believe that a car that is made for that 'crappy' 87 runs worse when u put 93 in? check out your knowledge in the burn rate of different octane fuels and why different engines require different octane gas, then decide if you should call the lower octane 'crappy'

 

87 Burns faster then 93 too

 

Check this engine out from SDPC:

I can personally verify that this engine is 100% compatible with a TPI intake because I just finished bolting mine onto one of these crate engines tonight! The only thing I didn't like about it is that the cam is smaller than a stock L98 cam. They say it'll produce about 285 HP with that cam. I went ahead and added an LT4 HOT cam and 1.6 RR's to my engine though, which brought the total up to $3300 (including tax & shipping). This combo should be in about the 340+ HP range I'm guessing.

I'll let you know how it runs tomorrow after I drop it in.

Sounds nice, but will it run on 87 octane and will it/would it accept all emission equipment? Tell me as soon as possible as I am VERY interested in this....and do you think that you could possibly post that link up as it never worked, Thanks

The reason I need it to run on 87 octane is because in Canada 87 octane is $0.73/Litre and 93 octane is $0.90/Litre which is a big hike and I just don't want to pay that much extra. Normally it costs me about $30 - $35 Canadian ($48 -$56 U.S.) to fill up on 87 octane, and I really don't want to pay any more than I have to...I just want a TPI crate motor pushing between 270 and 330 HP but to accept 87 octane and emissions.

 

sorry reverse calculations...(sorry late at night and just came back from a bar)around $22 U.S. to fill up on 87 Octane here in Ontario, Canada. Just wondering how much it is down there?

i spend about 21 for 13 gallons of 87

when i put 93 its bout 26

phew...i thought you paid 50 bucks for gas!!!
i would be on a bicycle if i lived in canada. i pay 25$ to fil up in san francisco but gas is pretty high here. 185 a gallon.

have you checked into the 93-up caprice motor? thats what i had put in my iroc after i bent a rod in my old motor. i paid $1,525. at a local chevy dealer. your not going to get 350 hp unless you build it up. but if you do that you might not be with emission laws like your wanting. i put it in an 88 iroc and use the tpi, and am running 87. the guy at the dealership said with tpi i'd be making around 260 hp. not bad. not as much as i want. but with some of my little mods i think i'm around 275-280.

 

Hmm, the link works for me. Oh well, try this: go to http://www.sdpc2000.com and type this part number into the search field: 12493509

Also, as long as you don't advance the timing very high it should run on 87 octane, the compression ratio of the engine is about 9.6:1, so it's barely higher than a stock TPI.

Also, it will accept all emissions equipment, the heads are 50 state legal (I guess that doesn't matter to you though) and have an E.O. number. Every other thing that has to do with emissions you will be transferring over from your current car.
