Car is pretty light for a 5th gen. Going to see how it acts with E85 but going fuel cell as well and going to mess with some other fuels.
Awesome, looking forward to the progress. What is the weight of the car and which clutch are you using?
Thanks man. Last time I weighed it was 3750 with me inside but went to 15s, taking more out, probably kirkey and battery coming too before I get out to the track. Had a McLeod RST already but just got an aluminum flywheel for it, going to see how it treats me.
Definitely following! Sounds like one fast NA 5th Gen in the making! Look forward to progress!
Not familiar with Smeding's cranks. Is that one of those slick eight center counter weight style of LS cranks?
Which lifters?
Appreciate it! That’s the goal anyway. The Smeding crank is ordered straight from the foundry from Smeding. They’re located in San Antonio and that’s where my bottom end was assembled. I have some Johnson 2110Rs currently.

Thanks it’s appreciated. I hope I can make it to my goals. The Smeding crank is a 4340 piece that isn’t outsourced, they receive them directly from the foundry. So it’s not a rebrand or anything. I have some Johnson 2110Rs as well.

You may have issues with the clutch but hopefully not!

yeah I’m hoping not. Fully going through the system and getting all the good pieces like the tilton slave, aluminum flywheel, tick adj master, braided line, etc. Hopefully that RST will take it
Definitely keeping up with this thread. I'm getting ready to start on a new build for my sons car. 4.070 but keeping the CR around 12.5. It will have a Cam Motion LLSR setup though.
I haven't decided if I'm going square port or keep cathedral.
It's a 3 event car (AutoX, Roadrace, Drag race) so I like the cathedrals for the torque they produce.
My son is dead set on staying NA, so I'm quite sure I can squeeze well over 650 rwhp on gas and more if we go e85. This is also a street driven car and one of his things-to-do is Drag week.
His current engine already has so many things I'm gonna use in this block. Forged assembly with many personal touches, scraper, etc. All I need is pistons and rebalance. The 408 now is 10.8:1 and makes over 530/510rw on 93

650whp on 93 will be something. My sbe LS3 made around 580+whp on the previous setup. Shelf cam, ported and milled stock heads, fast lsxhr manifold, 1 7/8 headers, 103mm tb, UDP, and E85. All of those little pieces will definitely add up.
My personal opinion would be to step up to a link bar lifter like a Johnson 2116 or 2126. All that money into the engine, I wouldn't want those plastic trays in there..

Kind of the one iffy thing I wished I had changed. Unless there is someone looking for what I have plus cash on my end Lol
FWIW - Speaking of McCloud RST's, in 2017 when my T/A got a RPM Transmission Magnum, RPM vetoed my idea of an RST. They'd seen RST's start slipping after a few hard launches by cars making ~550+ whp. They insisted the McCloud twin disc RXT would drive basically as well and hold up much much better.
I think this 416 will be too hot for a RST to hold up very long to hard launching.

This is why I dont think it will hold up. Vette guys were having trouble with it around 550-600 and hard launches at the track. Its not the components around the clutch, more so the clutch itself isn't able to handle the abuse. If the engine is still out, I'd replace the clutch with the RXT.
You know what, it slipped my mind when I first read it but you're going to want to swap out those 2110r lifters. Not because they are not link bar'd but because they are not rated for the spring pressures of the PAC 1209x springs. I just had issues with mine. The previous owner of my car put those lifters and springs in and the springs were collapsing the lifters. Worth taking them out now instead of having to do it down the road.
