I WAS listening, PLEASE help now!
however, after spending the afternoon trying to get a tuner to dynotune my ride.... and no one wanted to with boost and cast pistons..
I called the builder and put my foot down!
so, I have gotten him to agree to pull the motor and replace the pistons with forged and put in a new cam.
Likely I will have to pay for the parts, and he will supply the labor.
Not exactly fair, but I need to move forward and this seems the only way.
SO, the question is, what parts? I will still have a cast crank and rods, 202 valves in the stock 113 heads, edelbrock highflow intake and base, p600b super charger
what pistons/compression and what cam should i use?
price is a consideration but i do want to make pretty stout power at 5k rpms and below.

- Budget?
- Planned usage?
- Define "stout". 400hp? 500hp? 600hp?
- Planned level of boost?
Above 500hp I'd move away from the cast crank and rods.
FWIW...I'd also put money into better heads.
You already got the blower on there put together and running?
Noone will touch it even with a few lbs of boost? Gotta be someone
You got what you got. If you tear it down leaving the stock crank/rods dicey. Might run for a long time may be sweeping up parts.
Remember youll probably have to balance it too. Gaskets fluids etc it will add up. See your concern on your end too.
At this point have the mechanic help with a tuner....call it even.
Then piece together a stout shortblock over time yourself then put some real boost to it!!
I dont want to be stupid (er) i got taken pretty good.
I thought that rpm was the main killer with cast crank and rods, and i did not think 8lbs of boost would have really killed it.
I guess i need to take a calm look at my options, I jsut want t ogo have fun, tired of this nightmare.

Consider the current engine a mulligan and exchange the labor for a different pulley and what it'll cost to get someone to tune it with 4-6 pounds of boost. You do have the rest of the parts? Fuel pump, injectors?In the late 80s / early 90s there were a couple companies that used to boost otherwise stock L98s (including the stock cam) to the tune of ~425hp. Carroll Supercharging comes to mind. Some info that may help... LINKY
After the above, start the planning & budgeting cycle for a better short-block, cam, and heads.

I buy a short block, and heads and cam as i get the money, store them untill i have all the parts, then swap them out and sell my current motor.
I will be tie and money behind, way behind, but i want what i want, and there seems to be only one way to get it and be reliable. heck, i may even sell the whole car and get one with a stick.
any opinions on this short block?

a stock shortblock runs about 1500-2000, and mine isnt much better then stock.
the cam i have is one step above stock
I have 202 and 160 valves but with the current cam, I am probably losing power cus the valves are to big. Yes, I have a bunch of new parts, but parts that are not suited to what i want to do.. so, i didnt really get much value for my $5300
For 6 grand I could have had a longblock with full forged rotating assembly and dart heads. and it would be fully ready to accept the boost, probably more then the 8 lbs i was planning to run.

I got hosed, I trusted a guy who said he could give me near 400 horse for 5 grand, and 600 horse on boost. I believed he could deliver on it, because i knew i could get near that for the same price on a crate motor.
The last time i worked on a car was in 93 or 94, I had never heard of hyperutectic pistons, only thing i knew about was cast or forged. he said he selected the right pistons, and i believed him.
It is very difficult to face the fact that i got screwed and basically need to start over, and i do appreciate a lot of the well intentioned advice.
I am not stupid, i was ignorant, and a little gullible.
so the question is....
is there a safe level of boost i can run with a cast rotating assembly, if so what is it.
will alcohol injection take part of the danger out?
I cant afford to start over, some of you may be rich, but im not, this was a huge layout for me, and it will be years before i can shell out another 6-8k on a TOY car.
I have maybe 1k left in the budget that was going to go for the gaseous intercooler injectors and pump, and was hoping to come up with another grand over the next several months to finish it off and get it tuned.
If i cant figure something out I am stuck with 250 horse and a supercharger in a box after shelling out 6.5k, I am SO not happy, bought the car to brighten my life after a ****** divorce, got screwed over and now I am being quoted one liners... thanks thats helpfull!
anymore helpfull sayings? a stitch in time saves nine, would also be applicable in this situation.
Oh, one more question. Is your supercharger a kit that is actually made for a C4 Vette?
