To all you blown guys:

1) what kind of work was done to your engined to prepare for the SC?
2) what kind of SC's are out there?
3) most important, how much and how fast?

sorry, im new to this power adder stuff.

 

what size engine 305 or 350, no prep needed for a basic vortech s-trim or procharger P1-sc

 

L98. What kind of power gains am i looking at with one of those two? $$$? thanx

 

40% to 60% more power and around $3000 either one

 

I would definitely go for it if it weren't my daily driver. How would it hold up in terms of mileage and durability as a daily driver? If it's not too good, i'll have to wait until i get another car then bolt one on

 

if you get a 9 # kit youll be fine

 

9#? Are you referring to 9 lbs. of boost? If so, will i still get enouh power improvement to make it worth while?

 

absolutely

 

i have a question as well i have a stock 5.0 ho except for custom chip and exhaust. i wantes to get a supercharger is 9lb boost all a stock 80 k on the motor can handle? what about 12 lb?

 

Paul, awesome car first off. Yes a stock engien can handel up to 9 lbs at best, anything more will put to much stress and serious shorten the life span of the engine and you might put a pistion through the side of the block.

If you replace the internals, pistons and rings with forged stuff then you can ride that boost up to 12lbs.

For mine I am planning on replacing the pistons and rings when I stick my need heads on. L98 Aluminum heads on a 305 with forged pistions and you'll have a low 12 sec 305.

Of course headers cam and the right igintion will help. If you don't have your ignition upgraded for better spark and at least a full free flowing exhuast don't be bolting things on just yet.

 

thanks pennyless i have the headers but was waiting to put them on when i tore down motor for a supercharger. what ignition whoud i use msd 6al? was thinking of a cam as well but if i do that i may freshen up the motor and get some heads and porting done........AAAAHHHHHGGGG!!!!! all kinds of decisions.. but for now i will stick for ignition s/c and headers if i do a cam now what would be a good streetable choice?

 

Ignition is really an easy one at that, MSD, Accel, Comp all good all around the same. Try a new coil, some 8mm wires and new igintion box. Maybe a distrubutor its up to you.

A good cam for that 5.0 HO >>

But with headers and some ported heads and the ingintion you will see some kick *** improvements, SERIOUS POWER GAIN before that S/C goes on your car, go to the track before you get the S/C you'll be ****tin a brick.

305 TBI yeah that is a pointless build up but 305TPI its worth while if ya ask me. Look at ******* car

 

I've been told that the Comp 268XE is a nice cam. Mark Shields is doing the swap now. He should be done with it tomorrow. Thats what i'll be putting in my L98 too. You gonna come out and cruise with us? Check out the Mid Atlantic board. Later

 

Paul,

I have this cam on my 305 and I like it a lot. Infact it's brilliant! However, it's designed for 87 up motors with hydraulic rollers which your 86 doesn't have.

thanks for the reply i was misinformed i was told i had the rollers so i guess would they make a comparble cam for a 86? also what will it inprove low end as well as top end?
