"Day2" type BBC Build Up

[4onthefloor]

Im having a 454 BBC Built up for my 1967 Firebird, The Car is "DAY2" style And I want to build the motor to RUN & SOUND the part-So far I have the parts I need for the look-But Im having some trouble as far as Picking a Camshaft-the motor has a Solid Crane powermax roller "nitrous" Grind- 246/254 -114 LSA - 615/636-I had A LOT of issue's with it-So I want to swap it out for a Hydraulic Roller from Howard Cam 242/242 110 LSA
620/620-Also I have 3 Different intakes I can run with this- 1st choice because it looks Cool is the Older Torker single plane that mounts carb at angle, Then 2nd is an equally old Holley "street contender" it is a low riser single plane with a "WINTER'S" Casting mark So it almost looks Factory-Then I have a Modern Edelbrock Performer permashine Dual plane-I also Need some Info On the Best Fit Headers to fit this car-Any Input as far as PROVEN BBC Combo's is appreciated- I had this motor in my Bracket car & Im having it Refreshed- its about 10:5.1 CR- 290 Large oval port heads with large valves heads all done up-BOWTIE Rods-Fully STUDED-Upper&Lowers-& I Want to have it RUN POWERFULL on the street AND strip-its going behind a Muncie 4 speed with 4:33 REAR Cogs..

The vintage Torker is a Day 2 favorite as well as the Edelbrock C427.

I would say try the 660's if you don't want good street manners or care about any fuel mileage at all. I just posted on the same issue over at Steve's Nova Site.

Yeah I dont Care about Fuel mileage-I want it FAST&amp; to look Old school-If I had the money ,I would do a Blower with 2 four's.. I am gonna drive it on the street And take it to the Track..My budget says use the parts I have on Hand, A tunnel look's So MEAN -But my budget is VERY tight this time around-Im looking for most bang for my buck...

Im having a 496 Stroker built-Its a copy of a older Linginfelter build-it's about 612 Ft lbs of torque on pump gas-So far -I have the Day2 Gold Moroso Valve covers-New in box-Vintage Holley Street Dominator intake-Fly Eye-Im gonna Mount some older Thrush Mufflers-I willpost some pic's As soon as It gets done at the machine shop-With this Motor with my M22 -it should be FUN!!

I would sy Tunnel Ram would give you 60 to 90 hp more and there is the &quot;WOW&quot; factor.

The trick for Tunnel Ram for the street is idle circuit too rich. Restrict the idle circuit in the metering blocks and run vacuum scondary carbs. I have run them for 20 years.
