So we had to find someone else. We called upon old friend Scott Walker who certainly has the qualifications: he has worked at several name engine shops over the years, worked at the Frank Hawley school, and had his own shops, both engine and chassis. He has recently started a new engine/chassis business with Bob Braun, who is experienced in the sprint car and street-legal racing scene. This guy will be around for a while as Editor Jeff Burk reportedly has compromising photos of Scott Walker in the DRO files.
So, if you have an engine question, just send it to email@example.com and then watch this space for an answer from Scott.
What do you feel is a safe cr for street use - 93 octane pump gas - with steel heads? I would like to use as much as possible, but would be willing to change the cam or cut the piston domes down. Cam is 242/254-115 @ .050 lift hyd.
Now you can use 93 octane gas and I would add octane booster.
Keep in mind that your 115 c/l cam is designed for 4-speed application.
I raced it last year and ran 9.2 in the eighth-mile. This year I want it to get into the mid 8's but still be drivable on the street. Any ideas?
I also ran a Holley 4150. I think it was about a 600 cfm. It also has a cast crank. Anyway I want it to contend on the strip and also be feared on the streets. What would you do if you were me?
Here are my suggestions:
1. Up the compression to 9.5:1 and you can still use 93 octane pump
This should get the results you are looking for.
