How will it perform?

-Boosted- said
My build is getting real close to being ready to test on the track. Any guesses on how much HP the engine will make? What about ET and MPH in the 1/4?

408
12.5 CR (flat tops with valve reliefs)
Trick Flow CNC Ported with titanium retainers (I don't have the flow numbers but they are available online)
Solid Roller Cam - 660 lift, 258/264 duration at .050 108 LCA
HS roller rockers (1.5's)
Thumper 950ish carb on a Victor 340 and HVH 1" spacer
Hedman Huster headers with 1 7/8" primaries and 3.5 collector

727
Reverse Manual Valvebody
5800 PTC non-lockup

9"
4.10 gears and spooled.

'73 Duster (3000# with me in it)
Caltracs
Calvert mono leafs
Calvert shocks front and rear
FirmFeel uppers and strut rods.

Thanks in advance.

Bill I like everything about that engine combo, converter stall, rear gear since you run 1/4 mile. I like a little more cam duration but that’s me. Great headers and Thumper carb is also a plus. My question mark is the TrickFlow heads. A member is running some nice 6.50-6.60 passes at keystone and posted his combo but I can’t remember his cam choice. The first port I checked on my TrickFlow heads hit the advertised 300cfm. But I also found one terrible port and on that maxed out at 290 then dropped. Hmmmm. I can’t wait to hear your results because I know from following you I’m sure it will run great. I’m hoping to see it in the 9’s soon.
