B1 Alum Block Combo - What do ya think? - 01/16/14 12:16 AM
I have gradually started to collect parts for an engine that I am hoping to build in the future. I am planning on putting this engine in my 71 Demon Super Street/ Hot Rod car. It is a 4 link back half car, 16 x 32 slick. It weighs just over 3000 lbs. My goal is to run 150 mph on the stop.
The hard parts that I have so far include a world aluminum 4.500 bore block. A set of B1 original heads, B1 intake, 1.8 Jesel intake rockers and 1.7 exhaust rockers, I also have some of the other required parts but nothing else that is important in the combination. My plan is to collect parts over the next few years so it is a clean canvas.
Head flow Numbers
lift int. ex.
.200 170 130
.300 257 178
.400 318 230
.500 359 273
.600 383 298
.700 405 311
.800 416 317
I have looked at all of the various strokes that are available and I was initially thinking about a 588 but I am now thinking about a 556 combination
I would accomplish this like this
10.720 Deck Height Block
4.500 Bore
4.375 Stroke
7.100 Rod
1.4325 Compression Height Piston (14:1 Compression)
Do you guys feel that this combo would accomplish my Goal??
Any real world experience would be welcomed. Also this is a combo that I have not seen too much of. Is there a reason or something that I am missing?
