I recently purchased a 1991 L98 automatic with 221,450 miles from a forum member. I'm starting to plan for the rebuild of this engine. I would like to stroke it to a 383. Is their a recommended shop in Austin, Texas? I would need them to remove, machine, reinstall and tune the engine. Also , I am open to any suggestions that should be included with this rebuild. :yesnod:
One group NOT to use is Autotek. They did a stroker motor for me in 2000 for my C5, re-used cam bolts which are stretch bolts and my motor came apart about 2000 miles later.

Wow those valves don't like it when the timing chain breaks
There is a fellow named Chris whose shop is in back of Elite Motorsports I believe. He has done some great work. Don't have his number though...sorry. Someone will post it.
I just contacted Scoggin Dickey about some alternatives to building my existing engine. They have a Vortec TPI crate engine that puts out 357 hp and 405 ft/lbs. Has anybody used this crate motor before? Is Scoggins Dickey a reliable/ Knowledgeable firm? The cost for this engine is $3,400 + headers and custom burned chip. Besides the removal of the old engine and installation and intake swap are ther any other foreseeable costs? :confused:
I have no personal purchase experience with the guys from Scoggin Dickey, but they have been around for a while. I have talked with them a few times and they were always courteous and helpful. There are always extra unforseen expenses. Coolant, new heater/radiator hoses. I would have the radiator cked to see if it needs repair with 200,00 miles on the car. How is the suspension, ball joints on the car, wheel bearings? A high mileage car is not necessarily bad, but it will need to be maintained and may need some of the items I have mentioned if they have not already been serviced/replaced.
Has anyone used Austin Corvette? I have talked to them and they seem very knowledgeable. The Owner indicated that it would be $6-7,000.00 to stroke the motor and tune. Any help please.

Scoggins-Dickey is very reliable and well known for their OEM or "one off" OEM equipment. They are sort of like today's Yenko. I think the new Vortec TPI is the way to go. The Vortec heads are much better than your original L98 heads and will probably make up for the difference of the additional displacement of the stroker motor. Plus, you'll get an improved lower manifold designed for those Vortec heads. Considering it's a new motor, I think it's the way to go. You could probably get that local shop to install it. I amagine after adding labor, headers, etc, the total cost will be in the $6k range as well but you'll wind up with less headaches later w/ the crate motor instead of the stroker.
Chris, Austin Corvettes are courteous. But they did charge me $160 for the fuel pump and 2 hours labor to replace it. Granted it was done right, but from that alone, I doubt I will ever go back.
Not Austin but not too far to leave your car. Call 21st Century Musclecars here in Carrollton, Tx at 972/417-7177. This shop is Lingerfelter authorized builder. good luck. :smash:
I decided on a fast burn 385 crate motor. It is scheduled for delivery on Wednesday. I have also ordered the miniram III for Fastburn heads and a 58mm throttle body. As I'm waiting for all the components, I keep kicking around the idea of removing and replacing the engine myself. I have been reading the Haynes manual and it appears to be a straight forward removal and installation process. I have some previous experience on none electronic control vehicles. Is this something that is recommended or should I spend the $1,300.00 to have someone install the engine?
Snowman, those cam bolts can be reused many times. Autotek either didn't apply locktite, overtightened them, or undertightened them, but reusing them wasn't the flaw. Wish you'd asked around before you chose autotek, there's at least 100 people in austin that are doing all they can to steer people away from there because they got burned.
