Got a small shipment of BBM blocks coming in hopefully in the next week or two. One of them is earmarked for a 465 cube bracket engine build for Steve Dodson's AFX Falcon.
Specs are:
*BBM block, 4.310" bore
*RPM 3.980" steel crankshaft
*Molnar 6.800" rods
*Custom solid flat tappet camshaft, 262/270 @ .050", 109 LSA, .640"/.660"
*Trend tool steel solid flat tappet lifters
*Custom Racetec flat top pistons, 12:1 compression
*BBM Tunnel Wedge intake
*Custom Quick Fuel 725cfm carburetors
*Trick Flow cylinder heads, ordered bare, assembled with small diameter dual valve springs and titanium retainers
*T&D roller rocker arms
We (collectively as a forum) have been struggling with good comparisons for these cylinder heads. The goal is to do an engine with really only the cylinder heads as the variable to at least get a feel for how well they do. I think the 390 I just dyno'd did pretty stinkin well for a relatively simple combination.
In this situation, I have a 465ci Tunnel Port engine that I can compare to. Basically the same compression ratio, same bore/stroke, same rod length, similar camshaft durations and LSA's, same carburetors, similar-ish intake manifolds, etc. That TP engine made 696 hp and 588 lb-ft of torque. I expect this one to be pretty healthy as well.
