The new Mill for the BadAssGN
 

Here is some parts and engine I am working on, been one busy spring but I got time this week to work on it.
Still need to build the oil pump,install the cam and front cover, both heads are on now, and I'll install the intake before it goes in the car.,

I'll post a Vid of the first start up, prolly next weekend, who knows.

Here goes. it you don't like buicks these pics are not for you...

if you are interested, there are some pretty significant modifications here.
Forged pistons, Arp main Studs and billett steel main caps, arp rod bolts, rods have been polished and shot peened, so has the Crank, I'm using a special hardened rod bearing and 3/4 groove main bearings, there is also modifications to the oil system, the heads are Raace ported and have the largest valves you can fit in stock casted heads., I run a cam suited to street use but proven well into the 10s. this engine will run clean and fast all original emission equipment will be in place.

looks good man :smilie_da

if you had 2 more cylinders youd be cool, 2 less and youd be as cool as me :D

oh and get ready im gonna have 200 posts soon, you know what im talking about :D lol

looks good though man its pretty. wife know you spent the vacation money on something much cooler yet? lol

The Wife has no idea how many thousands are into this build... and she'll never know...right guys....:la:

I love turbos

lol my old man thinks my motor has a basic rebuild....yup with aftermsrket parts, lol.

bill you send me that package yet? its your insurance for keeping me quiet, lol

yeah no kidding about valve size, what modifications were done to the oiling system? Did you change releif valves or change pump gears or modify the pump?

All of the above.

Some use a high volume kit, I don't like those because they put added stress on the Cam gear that drives the pump and I've seen failures.

I also modified the front cover to promote better flow, as well as a booster plate a R&D team came up with in the 90s.

I also Drilled out the oil passages for the two centre mains, these mains feed two rods each so i focused the oil on them.

one other trick is to Drill smaller holes in the cam bearings to reduce the volume of oil the cam gets and make the mains Priority.

very nice, can't wait to see the start up vid and also see what it can do

What kind of sump are you running and what differance in pressure are you going with the new releifs?

Well... stock sump holds 6 litres. and the oil pressure is a problem with these engines. I've seen many with 10 psi @ hot idle, and a max of 50 psi

My engines see 20 - 25 psi hot idle and 60-80 at 5500-6000

the extra flow to the centre mains is critical to longevity at high HP (500 - 750 hp)

Mine should see 550 or so to the wheels...

Give me the cylinder heads and she will never know. :smokin:

I can do a set for you, but they ain't cheap. I have a lot of hours in these particular heads, I doubt I'll ever do a set with this much port work again.

well it all looks pretty bill, lets hope it stays together long enough for me to drive :D

I'm sure it'll be fine, I've checked every clearance you possibly can.
