It's for sure possible with a 18* setup. I have a used 355" 18* shortblock assy. for sale here on RJ #1059801 that made 700 hp @ 7900. You can find 18* takeoffs on here and other sites for around 2k to 2.5k. If anyone wants a better look at the build/dyno sheets I'll fax or scan 'em, just PM me. You will need to run offset lifters and shaft rockers, except on some of the Brodix 18* stuff maybe? But to answer your question yes that kind of HP is done all the time. 8) JB
