RMVB th350 I'll install next month after I get it running and tuned on the stock tranny .
then a Huron t4 kit in February. ��
Here some pics: 20 years old and never even had a valve cover off of it . Check the birds nest in the back lol Ill take more pictures tomorrow . The power steering pulley was so brittle it snapped into 6 pieces when i put the puller on it . After soaking it for an hour in pb blaster. This is going to be a fun project My "shop" setup lol I think it sat for a for a few years lol maybe 8-10 Better !
All torn Down! Need a Sawzall to cut the driver side Manifold off. bolts and Nuts are straight RUST! Dollar Store Oven Cleaner FTW! Oops Looked at the cam bearings... lol The SHAFT! Aaaaand Shes in!
Good times. The exhaust note is going to be something different than what people expect for the tuneability/drivability/maxHp. Keeps the turbo spooled.

No turbo here hahaha . Using it for N/A And maybe a little nitrous
Hopefully it sounds very close to stock . That's the goal . Stock Catback FTW
Ready for some head ! Heeeeead Almost ready to fire . My headers, fast 92, and powersteering pulley wont be in until monday . So i bolted the stock manifolds/cats on. And the ls1 intake/stock lid on to fure her up
And she runs!!! Very smooth!

Congrats, you are a cam swappin’ Pro obviously. Could pass for stock with a quiet muffler . A closed exhaust system will hardly put a dent in power production at part throttle or WOT. We’ve optimized blowdown without introducing overlap. Slight seat timing overlap for low emissions and/or boost if ever used that way. The intake opening earlier for more net flow on the intake stroke. The lobe design and .600 lift should make it the most power-producing cam for its idle quality. Tune and have some fun with it. It wouldn’t surprise us to see an increase in fuel mileage with reduced pumping losses if you can keep your foot out of it . Mind if we call her, the Sum-8715 -the Ghost cam?
