Actually Chas, I only have around 1.7 horse/CI
The engine is a 450 inch SBC. Tall deck Dart block, Dart 15* heads, Ohio Crank rotating assembly. Dart intake with Pro-Systems carb flowing 1000cfm+
Cam is Lunati .736 lift Intake .696 lift Exhaust
290@.050 300@.050
Advertised duration 328 338
Cam also has 4-7 firing order swap Lobe seperation 106
Springs are 210 closed 605 open
Crower roller lifters and T&D rocker assembly
Lunati says this is a 410 sprint car cam, but the extra inches help tone it down a bit.
Also running an MSD box and an E-Curve distributor
If I remember correctly this combo can be bored and stroked to 482 inches.
I limit RPM to 7500 on the street and 8000 at the strip. Also a 4000 RPM stall converter
Because the
oil pan rails are wider than stock, I had to have Moroso build a custom 9qt pan. Since this is basically a racing block the only
oil pans would have hung to low for the Cobra. I think pan is 7 inches rail to bottom of pan and 13 or 14 inches side to side, with 5 trap doors.
The reson I went with the tall deck, I wanted to run a taller piston so I could get the
oil land above the wrist pin. I've always had an oil control problem with short pistons, not to mention piston rock when the skirt comes out of the hole.
