My friend tried this and although it was making amazing torque from 3000-6000 RPM it was breaking factory pistons, I think the factory 455 pistons just aren't up to the task.
He is now building a Buick 350 twin turbo on a budget, here is his combo:
- 67mm Turbos
- CSU Holley carb
- TA Singleplane intake
- Home ported iron heads
- Stock bottom end 350
- Custom Scott Brown turbo flat tappet cam
Mark Burton is currently finishing up a similar setup with the exception of EFI and a roller cam. We never did have any issues with the stock bottom ends of the Buick 350, even with 20 PSI and 7000 RPM.
I am doing a more serious 350 with a block girdle, billet crank, nice rods and pistons, ported alum heads etc and turbos... Still way less $ vs the aftermarket blocks.
You would need to pull it apart gap the rings and put a cam in it to pull some low end torque out of it so it lives.
He was gapping the rings but no luck... Lost 7 pistons on various cylinders in 7 different attempts. The plugs were happy and 02 sensors showed it was tuned fine. I'm sure with a better piston it would be fine.
Well I'm going to guess since ots been almost 2 months since the last flurry of post and we haven't heard s response back from TA, that 1 of 2 things is going on. 1st is nothing has really gone on. 2nd is they are not telling us much more till they are closer to being ready
They'll post something soon.
In other words, they hope you are READY to make SERIOUS power, but hopefully not READY right NOW!
Just a quick update. I gave up on thinking we would get the NEW Stage 6 cylinder head machined in house. So, I contracted the same company that machines our cylinder blocks. They have been working on writing the CNC program and fixtures. Hoping for a few machined heads in the beginning months of 2021. I have a couple sets plus some miss run heads to be used for machine set up.
I was thinking about these heads when I saw all the updates on the TA Wagon.
