1994 caprice "the bad" with 3 inch exhaust

Video of "the bad" with 3 inch dual exhaust, and 40 series flowmasters.

The car is currently under construction with 138 hours of work (about 14 working days) over the past couple of months.

Started with a 1986 caprice frame and a 1994 caprice body and the drivetrain from "the ugly" (1982 el caprice featured in one of my other videos.

The 3 inch exhaust came with the '94 body, took a lot of work to make it fit.

Also has flowtech headers, 1 3/4 primary, 3'' collector. They are for a 77-87 cutlass. Passenger side bolts right in. On the driver side the flange, tubes and collector were all cut apart, reangled and welded back together. If the engine didn't have a diesel starter (huge gear reduction unit) the driverside would have fit with some dimpling of the tubes and cutting the collector off to change the outlet angle.

Still have a few mechanical issues to work out (like the whistling air bleed), then the engine wiring harness needs to be re-done, then body work.

Update: Got the car painted and on the road by January 3rd. January 31, 2008 the engine started knocking. Sounds like a rod bearing. So Oldsmobile engines are good for 35 years and ~300,000 miles.

Update 2: Replaced the first oldsmobile engine with another from a '73 Omega. Lasted through the winter of 2008/2009, rod knocking. The nylon cam gear teeth started coming apart, blocking some oil passages in the crankshaft. Busy with other projects, but am working on rebuilding this engine as the bores were perfect still had some crosshatching with ~120,000 miles on it.

do you get enough back pressure becuase im going to put those on my car withing like the next two weeks

[capricechopper]

@josh666675 Back-pressure = bad. Only reason to ever worry about it is if you have a EGR valve that requires back-pressure to open. Can always put a regular EGR valve on...

just brought a used cop car--94 Caprice 9C-1. My 95 caprice 9C-1 was stolen around the end of April. Never looked into the motor, just wondering, does it have the roller rockers, 1.5's or 1.6's? stamped steel? I would like to add 1.6 ratio rockers and maybe upgrade to a LT4 cam.

@BNforever2009 Sucks about your '95. I have yet to own a LT1, mine has a 1973 oldsmobile 350 in it. See the description for further details. However my understanding is they still used the 1.5:1 ratio rocker arms, that are stamped steel. The lifters are roller though. From my days on the f-body e-mail lists, I know the camaro guys were putting in the LT4 camshaft, but I don't know what modifications are needed to make it work correctly. Probably have to tune the ECU.

@25foot ...yeah if Jessie Duke was alive today this is what he would be driving!

If I didn't know any better, I would say that is a whiskey running car.

would you know if a 91 camaro 305 tbi toliet bowl injected lol has a egr valve??

[BNforever2009]

I knew a lot of guys running those 350 olds back in the day. had a former friend running that motor in a 71 Chevy Nova and his uncle had one in a 79 Olds 98 Regency and that thing could run too. Yea, im thinking running 1.6 roller rockers or going with a LT4 cam and 1.6 roller rockers and new valve springs.
