A few parts for my next engine - ZR-1 Net Registry Forums

tpepmeie · 12-31-2008

Howdy, guys. Thought I would share some pictures as the pieces are slowing arriving for my spare LT5 buildup. The induction system is out being ported as we speak. I know my limitations...I'll let an expert build the bottom end and assemble the motor, but I need the market to turn around first to free up more capital!

Carrillo tapered H-beam rods. Stock rods weigh close to 750g, Olivers are around 650g. These are around 550g. The 4.00" Bryant crank has 2.00" journals.

Custom ATI super damper. Yes, it took over 2 months after the drawings were approved. The three pieces are the damper, pulley, and crank hub. It is about 20% lighter altogether than the OEM piece.

And last the mechanical buckets.... about half the weight of the GM hydraulics. Still not entirely decided to go this direction. Need to decide this spring before I order cams. The small pieces are the shims for lash clearance adjustment.

I forgot to snap pics of the new springs and Ti retainers. Will try to get that later.

tpepmeie,
Great pics and thanks for sharing.
Should be able to see some real high revs and power with the lighter valve train components.
Can you tell us where you found the mechanical buckets and Ti retainers?
And what piston/liner combo will you be going with and what is the power target?
Fascinating project.
Please keep us posted.

Great choice on the rods. I`m running a set of them in a 10 second dragboat with a 496 chevy. Also have another set of them here to turn a 1992 Chevrolet 454 SS pickup into a 496 SS.

Not to butt in...... This is my 402 build.

Moldex 4" with 2.00 rods

I went with Crower Maxi-Lite B-4 with upgraded bolts, 625g but I plan to hit it with N2O

Ron Woods Liners/and studs

Top end with be Mono runner into heads, From Greg VanDeventer

I like that ATI damper, can you tell me more on it.

flyin ryan · 12-31-2008

i deal with ATI on my higher end stuff. they really seem to be on top of the game right now, great stuff. been fair with me too, that's never a bad thing. your Dampr looks like it tuned out very nice, Todd. you happy how it turned out? i can't tell for sure...did you go with an aluminum hub?

Todd. Fastlane spent a ton of money and time on trying to do mechanical lifters and finally gave up. He felt the extra work needed to get the lash right did not justify the end gain.

Hey Polo,
Can you update us on how is the 402 build is coming along?

Polo-1 · 07-07-2009

Sure

The top end should be done 2-3 weeks

The block is in Spokane now. They need to make tq plate for the block. I think he said it will be 4" T-6.

ARP studs for the bottom end are a no go. I tried to have them made, no luck. I'm to small of a order, I guess. I wanted 5 sets made, no luck.

Ron Woods is working on having them made ( multiples ).

Everything on the LT5 just takes forever to get done. It has not been a cash shortage on my end. I guess if I did all the work myself it would go faster. I don't have Rottler boring and Sunnen honing tools. As porting, I'm only OK at it. I want this little 402 hit 625-640 (motor hp) then the NOS on top.

How yours doing Todd

Great work Todd.

One thing comes to mind reading all the posts. Remember all the bashing about how long it took to get a stroker built? Now that you guys are doing your own and encountering the same type of delays, it put it into proper perspective.

BTW, I am going to have full siamesed plenum gaskets made that are oversized on the outside shape (to cover the welded up areas, and undersized on the inside port area, so that they can be trimmed to fit each individual engine since the port configurations vary.

tpepmeie · 09-03-2009

Some new eye candy. Custom CP pistons arrived.

Unfortunately, these were ordered without the valve reliefs -- a mistake by the builder

. We've ordered a second lot with the correct valve reliefs. I also took the opportunity to make a few other tweaks to the design.

These will be for sale soon. Even w/o valve reliefs, they will handle some moderate cams.
