Dave Bamford's 4.8 LSX Conversion

[8 SEC 109]

NICE!!!
Hey Dave who did the block?

The short block is stock except for arp rod bolts and head studs. We disassembled the motor cleaned everything and opened up the ring gaps to .028. Again this is a $250 junkyard motor.

Looks like a cool set-up, nice alternative to the 109.

It's nice being able to call Summit or go to the local auto parts store for supplies, they are cheep and reliable too!

Ted stopped by the shop today to degree the cam. Set the heads and intake on for a quick photo.

This is a beautiful intake. Looks so clean and new, lol. Any idea what the heads are going to flow with this intake bolted on vs the stock?

Those are insane numbers. 310 @ .600 is no joke.

Not bad for a junkyard set of heads!

Awesome man... this seams to be the way to go anymore..Im kinda glad i never bought a buick with the 3.8/109, heard way to many horror stories. Urs being the worse for sure.If i remember correctly not even 500miles on it and it took a crap. Make sure you got the video camera when you fire this monster up!!!

I have been down the 109 and stage 2 road, this is the way to go! Price and availabilty of parts is second to none. When built by the proper engine builder or used in stock form it is a very reliable piece. 1000+ HP with a stock shortblock...priceless.

Nice! What motor mounts are u using?

 

[plowboy72]

I think this is the coolest thread on the board. Available parts and cheaper!! Plus more horsepower! For real "gear-heads" this is always a good thing.

I'd like to see what it puts down on e85.....
