The W5 i know of was my old car/ motor, but after i sold it. Guy who bought it has become a good friend.
He took what i had( 9 sec street strip car) and upgraded the motor. Lots stayed the same.
What it became was.
4.100 X block
4 inch stroke
Fully ported blue plug W5 heads with 2.08 valve
Jesel sportsmen rocker gear
276/282 ish 700 lift roller( aggressive lobes)
Brett miller modded Victor W2
TTI w5 headers
1100 gas dominator
Compstar 6.300 rods
Gas ported slugs( CP)
14.3 compression
In spite of the shelf headers, motor made 708 dyno’ed at Best Machine
Went on to run right at 140 @ 3220 on 002/003 leafs and 28 by 10 QTP bias tires
Went 135 at 3350 when i had it. Less compression, milder roller, no gas porting main differences. Maybe better East coast mineshaft air

.030 over 360 with a K1 four inch stroke crank, K1 rods, Diamond flat top pistons, .520 lift Racer Brown solid lifter cam, W2 econo heads I ported, Victor intake I ported, 750 Holley carb

App 2850 pound car at the line, powerglide with 5400 stall convertor, 4.88 Dana, 1 7/8 headmen headers, shifted at 5600 rpm. I think that’s everything
