Hey guys, I have been doing a lot of reading on the site regarding the maxima head on an N/A L28 w/ flattops. I was just looking at getting some feedback from the people who are currently running this setup. I.E. detotnation problems you encountered, valve clearance issues, etc. I should state that i have an N42 block w/ STD bore flattops, a 490/280 cam, tiple DCOE42 webers, and an aftermarket header. I plan on building this as a hot street motor that i will use ocasionally at track days. As well, where i live i can easily get 94 ocatne fuel @ the pump, so i am hoping this setup is capable at running pump gas w/ a full 36deg advance on the timing. Any input would be greatly appreciated. Thanks.
