Speakin o' early Firebirds:
Friend of mine, Tom Nielsen, asked me how to make his '68 Firebird faster ..
..I told him I could put a big block Chebby in it for about as much as it would cost to rebuild his 350
..and it would be orders of magnitude faster -evil grin-
We went junkyard hunting ..found a big port 396 in a '69 chebby station wagon.
Put 11.5 TRW pistons in, balanced, printed, stuffed a nice 550 lift hydrastic cam in,
tunnel rammed it with two Holly 750's up top, and put 4.88's in the back.
FYI ..to put a Rat into a Firebird or GTO, all you need are the mounts direct from Chebby parts counter..
..mounts, clutch linkage, throttle links for a Rat in a Camaro bolt into the Firebird,
..for the GTO you need the same for that year Chevelle ..also bolt in.
..and the Rat weighs about the same as the Pontiac 350.
It was *crazy* fast
..120mph to merge with traffic up an onramp, from the stoplight, f'rinstance
All kinds of Pontiac 'people' wanted to know where we had gotten the tunnel ram for the '350'
..he had left the stock emblems on.
..Tom useda tell 'em he carved it out of a block of aluminum
I ran him from a roll once in my 440 Duster .. Tunnel Ram 440 vs Tunnel Ram 396
..the big Rat just ran away ..far more power out of those big port heads
To this day Tom swears I was pedaling it just to make him look good ..I never pedaled it for anyone.
(unless I was ahead and feelin 'friendly' ..not very often)
