Mutt455

1977 Trans Am with 455 Injun swap and I decided on going with a Turbo 400. Has anyone on this forum ever tried that Lokar "High Tech" electric kick down switch?

Or retrofit am I better off Retrofitting in an earlier pedal mount switch?

If you are upgrading your brakes from non power drum to power front disc brakes then you will need Power Front Disc Brake Springs otherwise your car will nose dive under braking.

When you upgrade your brakes you might have to upgrade your rims? Good Luck - Mutt 455

stock heads, stock turbo 400 converter then I would stay with a "near stock" cam.

Stock 6X-4 heads they don't flow air nowhere near the stock # 16 heads.

I have a 1968 Firebird coupe with a 428 +30 over - wide ratio Muncie and a 12 bolt 3.5 posi rear.

The heads I use are 1971 # 96 milled for a compression ratio of 9:1 with Magnum 1.52 roller tip rockers.

Stock heads only flow to about 4000 rpm. Check Out the Wallace Racing Calculators and shift points - very informative.

I have too much rear gearing in my 1968 Firebird. My latest Firebird project is a 1967 with a Mutt 455 again # 96 heads un-ported.

The 67 has a 3.07 rear and Big Injuns seem to love either a 3.07 or 2.73 rear gearing for a street car.

Good luck - Mutt 455

Welcome to the site - awesome 65 Catalina convertible.

My Pontiac project is a 1967 F.Bird convertible 455 and upgrading to a complete WS4 package -

Not a show car - just a driver. For paint I was think Tiger Gold (paint and peel) with black TA stripes.

Just wondering if anyone here has actually used Alsa paint & peel for there cars?
