Found you pics Bill. The two opening you cut look super clean. It just baffels me that they didn't think to make the cowl functional. I assume it was for rigidity or something like that.

Solid shifting just sounds like he put a B&M shift kit in. Those are like 30 bucks. I paid a thousand for my beefed TH400 from a performance shop. But in ANY this GS cost more I'm sure.

I'll look through them. Thanks!

I have been looking at these hoods and the cowl looks closed in back. Has anyone opened it up for the added air flow or does everyone just paint it as is?

Anyone done their exhaust so it exits through the rear quarter panel? I love the look of the pipes through the panel but it doesn't look feasible. What options have you guys run other than the normal pipes out the back?

Finally got the car back on the road with the new trans and driveshaft. Put about 300 miles on her with no issues. Recently she started surging when at idle. Only about 200 rpm or so, but enough that when sitting at a light you feel it. Yesterday the rpm bumped itself up to about 1500 when in park, and when I shut her down I got a little post igniton rumble. I saw some smoke coming from the driver side breather so I added a PCV to the carb last week and checked for leaks around the carb with starter fluid but didn't find any. Any ideas what would cause this big change?

Update, turns out I'm stupid. When I pulled the driveline to do the floor pans I saw a few chewed teeth on the flywheel. So I replaced it and the starter to be safe. Well the scat crank doesn't have a nipple to line up the flex plate and it can go on multiple ways. So she was out of balance. Which I should have noticed but chocked it up to the new beefier motor. Only took me two transmissions to learn that lesson, haha.

Great Build! I was wondering if anyone has run the plate style nitrous kits and what they thought of them? I was thinking of running a 150 shot.

Thanks for the input guys

Replacing all the bushings out back and want to box the lower arms in to add some strength and can't afford aftermarket arms Anyone buy plates to weld in? If so where did you get them and were you happy? I've found some for chevelle, I assume these will fit mine as well?

Turns out the flywheel was out of place and with some repositioning she's now beautifully balanced. Thanks for the help guys.

Update* through some research realized that the SCAT crank that's in there does not come with a dowel pin for the flywheel. Apparently none of them do. So when I had some starter issues previously and I replaced the flywheel because of some partially chewed teeth I may not have aligned the flywheel properly for the external balance. Gonna back the trans off tomorrow and check.

Has anyone ever heard of having a balance issue and it only showing at lower rpm's?

Sorry, the entire drivetrain is new. 454 bored slightly to 468, Continental 9 inch converter, 168 tooth flexplate for 454 BB, Pro Sport Harmonic balancer, and a TH400. Poly mounts all the way around as well.

Got the trans rebuilt and back in the car and she's back on the road. Got a call from my trans guy today and he said he felt a slight vibration right around 2k that concerned him. He was worried there may be a balance issue with the crank and if not addressed would cause pre mature failure down the road. I know for a fact the passenger side header is taping the lower control arm and needs to be massaged in with a hammer. it has the correct flexplate on there but I honestly can't remember if the balancer on it came with it or was off my 402. Or could tit be bad maybe? Have you guys ever heard of any thing this before? He's a very reputable local guy so I don't think he's making it up. Just wanted to throw it out there if anyone has ever heard of something similar. Thanks

Only making about 550 but split the housing. All rubber mounts but still looking for the exact cause

Was considering upgrading, first thought was an Ultra bell but wanted to see what you guys used first.

Poly mounts for both.

Hey guys, So I just snapped my second TH400 bell housing clean through today. I thought the 468 broke the original because there was too much power. Then had a TH400 built the was supposed to handle 800hp. Less than 100 miles and it snapped clean across too. Anyone know of anything that tends to be the culprit here? Or do I just need to beef up the bell housing?

Ordered the harness this morning, they had a 12 day build time vs. the 8 weeks everywhere else. Thanks!

I got the engine harness from M&H a while back. Now I want to update the light side from the firewall forward, but everyone is on back order for 12 weeks. Anyone have one sitting on a shelf or know someone who does? V8 , warning lights, passenger side alternator with internal regulator, A/C removed Thanks Will

She is decently built, but not extreme. Street/Mild Strip the builder called it Externally balance SCAT 9000 steel crank 10.1 compression Edelbrock victor series heads 454-R Crane cam Int 234 Exh 242 Lobe separation 112 Intake center line 107 Overlap 14 @.050

Harmonic balancer is looked a little aged and I was thinking about replacing it. But honestly I've never bought one before, what shhould I look for or reccomendations for a 468. Thanks

I didnt look at it and pretended that it didnt exist. We have rached a mutually beneficial agreement that if it doesnt bother me I wont cut it off
