Default CMS C5 454ci build

Just finished up this build. We experimented with this cam and intake combo. We will be backing the cam down a little bit since the customer wants to start road racing.


Specs---

1999 C5 6 speed


LSX 454 ci

13.1 compression

WCCH Brodix Stage 2 Ls7 heads with CHE modded Ls7 rockers

25x 26x custom cam

Ported Fast 102 intake manifold and 102 TB

Halltech CF112 intake

1 7/8 AR headers no cats

CMS custom 3" catback

RPS street twin clutch

CMS custom 1 bar speed density tune


This was on 91 octane + some torco, customer will be switching to E85 in the near future once we swap the cam, which will significantly raise Dynamic Compression.

i would have to pull more timing out of it... the motor was built to run on e85... the large cam bleeds off alot of compression, which is making this doable on just torco and pump

Awesome numbers Ryne! Those are like FI numbers out of an N/A combo! Can't wait to see what this thing would do on E85!
