396ci Holden Project #1 fires up!
 
The results really speak for themselves. This first "Project 396" is a bolt together with off the shelf parts...
1) Factory 304ci block, fully machined with our steel 4 bolt main caps fitted, clearanced for our 396 "I" beam rod, nodular cast crank, forged piston stroker kit. Block is bored, torque plate honed, decked to square, machined with "O" ring grooves on decks and "O" rings fitted, modified oiling system.
2) 396ci Stroker kit as above with a final compression ratio of 11.9:1 is fitted to the short block.
3) Our custom CSBS-720-112 solid lifter flat tappet camshaft is fitted.
4) Our latest 2009 series alloy VN style cylinder head package with Ferrea 2.08" intake and 1.60" exhaust valves, COME dual 1.450" valve springs and moly retainers and locks. Positive stem seals, screw in studs, guide plates, hardened moly pushrods, Crane cast alloy street type roller rockers in 1.6:1 ratio (Ford Windsor type). Heads flow 636hp through intakes and 126cfm @10" through exhaust ports. Heads are topped off by our new alloy valve covers making valve lash settings a flash.
5) Harrop single plane intake manifold port matched (others to be tested) and out of the box Holley Pro Series 950cfm carb. Two inch open carb spacer. Did we mention that 586bhp and 502ft.lbs torque was made on Caltex 98 pump fuel!
6) Bosch HEI distributor boosted by an MSD 7 Digital ignition box and coil.
7) Off the shelf Pacemaker 1 3/4" Commodore Tri-Y extractors with 3" collectors replacing the normal 2 1/2" outlets supplied by Pacemaker. These are actually our dyno test pipes. Aside from the collectors they are off the shelf.
8) For our testing purposes we have also replaced the usual Rollmaster double row competition timing chain and gear set with a new belt drive assembly supplied by Heads Racing in New Zealand. This is to enable fast cam dial in, cam timing adjustments and cam changes without removing balancer and timing case each time. This is also a wonderful product for those building serious effort Holden V8's. The $1950.00 price is a bargain considering this is all CNC machined from billet alloy rather than being a casting.
What does it cost?
396ci Stroker kit...$3300.00/ COME 2009 2.08" alloy heads...$5000.00 a pair complete/ COME valve covers...$550.00 a pair/ Any COME flat tappet camshaft...$385.00
At this stage these are the main parts to make the 396 project become a reality. There are several intake manifold and cam choices and we will test a number of these soon. It's also easy to build a more conservative 500 to 550 bhp version that's daily driveable in either EFI or carb form. To do this and more you will only need our out of the box 2009 alloy heads with 2.02" valves priced at $3500.00 a pair.
It's never been easier to make LS1 type power reliably from your Holden V8...what are you waiting for? Call us on (03)9571-4204 or email come@comeracing.com for further assistance or to order any of our products. Trade customers please call or email workshop@comeracing.com
