[QUOTE="MalcolmV8, post: 15813868, member: 8854"] That'll be a fun motor. I've built a 10.5 CR motor myself. Also with cams, ported heads etc. etc. I went with the 2.9 Whipple Crusher and I'll tell you it'll more than surpass your HP goals. However be aware that once you go to a high CR motor the RPMs wrap up and down so violently and quick compare to stock it starts tearing up the lower pulleys turning over the big blower. So prepare yourself for that. I destroyed no less than 6 lowers trying to make that work with the 2.9. I even went to custom made setups with locking plates etc. Nothing was able to hold. I guess I was pushing it hard though and was running 30 PSI. [ATTACH=full]1462814[/ATTACH] So I stepped down to the 2.3 TVS and was pleasantly surprised with how much more bottom end it had. The top end wasn't as strong, was only pushing a peak of 24 PSI and most the pull was around 22 PSI but it still made over 800 whp with that TVS. Now that VMP has announced the 2.65 TVS coming out that may be a viable option to reach your goal. [/QUOTE]
