    212 vs 206 roller cam

    They both work great the 206 will keep the rpm down and is a little easier on the valve train. It's been faster/quicker I went 10.80@125 on mine.

    FS: 3.8L N/A engine - never fired, built several years ago $1100

    Prices are good for clarity: 040 casting is a normal production 3.8L 2bbl block.

    Impulsive 3.8 swap.

    If I trade up or see a 450cfm Holley for sale I'll grab it and try that. It's so weird feeling the power band "come up" on this cam vs the original KB cam, it pulled from idle to when you lifted. This has a 214/224 flat tappet I got from EK02, it's a good one, I'd like to swap this engine in...

    Impulsive 3.8 swap.

    https://photos.app.goo.gl/Y7Lp4GJhQfPYe96m6 I had this at Waynesburg Flashlight drags back in June. I rebuilt and swapped a 390cfm Holley 4bbl in place of the 600cfm Holley carb, the 390 sure drives really nice around low rpm even on the single plane KB intake. The 600 developed a off idle...

    Swapping a Chevy 5 spd (NV3500) to a Buick Before Black turbo

    Connect these two by: using ANY automatic transmission adapter for BOP to Chevy. Space the flywheel and pilot bushing/bearing the same as the adapter thickness. The later NV3550 has removable bell and tail housings which still do not help. Enjoy the swap

    Impulsive 3.8 swap.

    "In stock" turned into a back order until mid July for SCE Gra-form exhaust gaskets, canceled that for SCE embossed copper that were definitely in stock. https://photos.app.goo.gl/FQYnUv8RGpPn9eYe7 Then I brought it back to the home garage and drove it to work today. The vibration had to be the...

    Rjc bulletproof gaskets with arp head bolt ?

    I have not but Perhaps the only issue with using head bolts with RJC bullet proof HG kit is: the re-torque of the fasteners. Seems that the seal on the head bolt threads that go into the block would be compromised if using RTV to seal. Probably ok with a Teflon thread sealer but I use RTV on...

    Impulsive 3.8 swap.

    Welding repairs are done, this is the entire exhaust system given this is a small car. https://photos.app.goo.gl/WUfuxE4PoJns1jXe7 Back onto the engine work & figuring out vibration.

    Impulsive 3.8 swap.

    Torque boost I suppose these headers are really nice they were/are ceramic coated, this car has a lot of tricks these long tubes are some. Vibration occurred after revving the engine up very high while reversing in a road rage scenario. It's very annoying while at highway speed cruising, the...

    Impulsive 3.8 swap.

    Pulled home built rear sump oil pan off, just a few slivers of cam bearing babbitt from the cam swap a few years ago was only foreign matter, it was clean and oily otherwise. Pulled the rear main cap and this block has a rope seal, now it makes more sense all the oil under the car. I didn't see...

    Impulsive 3.8 swap.

    F*ck 😆 over a year I am busy though. Removal was easy until it wasn't for clearance in the general custom oil pan to cross member area. Engine will probably have to be reinstalled without the oil pan and put that on later. Other than the the oil leaks and one loose bell housing bolt everything...

    Heavy soot on pistons

    Could be but that seems to only heat up and clog the intake manifold.

    Heavy soot on pistons

    Probably just the nature of the engine and a stock cam on gasoline. When I had to replace the KB Xb1 cam and cut the heads on the 3.8 in my Impulse, that engine had a bunch of carbon on the pistons, it was .030 over 9.25:1 compression and ran really good.

    3.8 Or 4.1 NA High Compression Pistons

    Try Racetec for custom slugs. I had Earl Brown help setup and order a set for my own 10:1 4.1L
