Ok, just got all of the tuning bugs worked out. (Adv. timing to 17.5*) and the car is running amazing. now it is ready for the strip!
Any ideas on times for this?
(mods in sig)

3.8, cant really drop a pulley yet with the higher compression

I honestly think that you will be fine to go with a 3.5 or maybe a 3.6. After my tune I am picking up a 3.5 from a local guy. Or are you gonna wait till you get rockers?

I thought since you did the top end swap its now just like a L67, with the top end swap done dont you have the same compression as the L67. And if thats teh case you should be able to go to a 3.4 with no problem. I would have put it on there and tuned it with the smaller pulley on and saw what numbers you had.

The pistons in the L36 are taller, resulting in higher compression. Top swap doesn't eliminate that.

You do have to be careful, but I don't see why with your mods you shouldn't be able to at least get a 3.6" or a 3.5"

[b] 3.8, cant really drop a pulley yet with the higher compression i agree with what rook said. Since the pistons stay the same, the compression is higher than an L67 bottom end. This is why the 3.8 pulley on an L36 bottom end is equivalent to a 3.4-3.5 pulley on a GTP Originally posted by drummerboy1307:

The blowers in these cars are very hot, resulting in inefficiency to begin with, but the smaller the pulley you go, the lower the efficiency. I know that i could probably go with a little smaller of a pulley and be safe, but if i can advance the timing from 10-11* to 17-18* right now, then it is creating just as much, if not more power then a 3.5-3.6 pulley would.

I'm interested in seeing how fast you are. BTW, did you put in rockers or a cam? I can't remember if you did either and your sig only mentions the springs and retainers.

no rockers or a cam. i did the springs and retainers for the future. i read about changing springs and retainers while in the car and decided to do it while they were out. Rockers are next.
Im hoping for a 14.1 or so

I wouldn't be surprised if you managed a high 13 either.
Have you ever been to the track before?
