Built Motor

[cobraboy169]

Hey eveyone. I need some help. I am considering building the motor to my 98 Cobra sometime in the future. I want to forge the engine, clean up the heads, continue to use my spray, etc. I will use the vehicle mostly on the weekends to have some fun and at the drag strip. I want to start learning about the different companies that are out there that sell forged equipment. Also I'm not sure if I want to just clean the block or go with a 302 stroker kit. Let me know your opinions and results with companies that sell good forged products, and opinions on what parts to mix with the engine build. Also I would want to go with a 10.5:1 up to 11.5:1. What is the pros/cons of going or staying with either one of those two compressions. Thanks again.

93 is standard pump here(premium) on the n20 250-300 shot, it will be a 93 110 mix ....the car has a forged rotating ass., b heads with a 5 angle, ported short runner and comp cams ....it made 381 rear wheel naturally aspired on a mustang dyno on 93 octane and a very conservative tune

In Cali you wont find 93. Its only midwest and eastcoast I believe. I think its due to emission regulations out west and as you go further east youll find 93 for sure since thats what I had in Chicago when I lived there. As far as I know all these cars are designed to run on 91 and not 93 so IMO it shouldnt make a difference as far as normal performance goes. 91 octane is the min for high performance engines.
