congrats on getting her back on the road looks great!

 

thanks guys.

yeah im going to clean the heads very very well before i even start putting the valves in. i dont want any metal shavings in there at all. nor in the oil passages or coolant jacket. i test fit one exhaust valve last night and i ran a pieces of shop towel thru the valve guide and then used gun lube to make sure it went smooth. once thats all done i will use the valve grinding compound i picked up at autozone to seat the new valves to the seats. finall assembly will go together with ARP assembly lube before it all goes on the car.

one more thing i want to try is install a spark plug in the heads and see how far it goes in... i can check to make sure the ground strap ends up in the same location on them all.

 

Ok here is a newer update:

I took the car for a run at the track to set a base line before and after for the upcoming topswap. Current NA mods are:
-mild ported TB
-HV3
-SD headers w/ custom 2.5" exhaust
-180* stat, FWI

Results!!! 14.953 @ 91.47mph w/ 2.162 60' time Not as fast as my Old PB with the DOHC, but I did not remove my spare tire, jack, tools, speaker box, had 3/4 tank of gas and I have put on about 30-40lbs since that time.... the car did quite well.

The current plan is to install the top swap this summer. I have read that top swapping is said to lower 1/4 about 1 full second. with the extra mods im planning I hope for just a little more. The plan is for:

-Ported heads Complete
-Ported Blower In progress
-Northstar TB In progress with blower
-L76 Springs Planned
-1.9 Roller rockers Optional

 

Nice time!!! Lovin the progress man, and from personal experience, ported heads help A LOT.

 

not bad since supposedly stock times are 15.6-.7

 

Well considering the only major mods are headers exhaust hv3 and a tune.... It's not too bad at all

 

Ok more updates: I just got a set of L76 springs from the dealer today. the other day I finished and cleaned the SC case, rotor pack, and snout on the parts washer at work. To my surprise the SC had the upgraded green coupler already inside. I have a new one but will keep this one as a spare. I will be putting the blower together soon. I need to figure out the type of sealant needed to seal it all. the snout does not have a pulley on it. and the snout that has a pulley, the paint is chipping off. I don't want to have to change the oil twice and reseal it all again... so I'm thinking I will just get an MPS and put that on the better snout i have. Which leads me to a possible early mod 3.6" mps. So does it look like i have enough mods for the 3.6" I know scanning is the only way to be sure but with the mod list i have below a 3.6" should be ok right?


L36 bottom end
Ported Heads, L76 springs, Si Valves, viaton seals
Port matched Lower intake
Ported Gen 3 M90
matched to a North star TB. will be starting with a ported L67 TB first and doing a comparison.
3" MAF from my DOHC
Speed daddy headers
High flow 2.5" exhaust with High flow cat and magnaflow muffler
4t65e with 3.29's
180* stat
104 plugs

 

Here's what you are needing -should be available in most local parts stores to seal supercharger..

 

I used red GM gasket maker FWIW

 

Ok so just a little update on what is going on in 2-3 weeks...

Ported L67 TB (I have a ported Northstar may use it if I drop pulleys)
Ported M90 both inlet and outlet Stock pulley
Ported LIM gasket matched
Ported Heads gasket matched,
-intake and exhaust runners ported similar to stage 3 heads
-chamber polished and valves deshrouded
-Si valves with viaton seals
-G8/L76 springs
-Manley retainers and comp locks
-Intense light weight push rods
Existing:
Speed Daddy Headers, Magnaflow muffler, 2.5" custom exhaust.
FWI
L36 9.4:1 bottom end.
3.29 gears
DHP tuner and my years of tuning experience.

It is said that a topswap will lower your 1/4 mile times by 1 second. the heads, porting, and flow mods should be good for another .2th's the better springs and tuning should shave maybe another .1th So with track prep I am aiming for mid 13's

Here are a few pics of the Blower that i finished paint on today. the Vac lines are all hidden. I will tuck the injector harness and wires behind the rail to keep the clean look. I just cant wait to get it on the car.
