I have a 1970 454, 280 comp cam with ported 69 425hp 427 heads. Runs out REAL STRONG in my hotrod. Im figuring approx. 450hp. Friends stop over with their new trucks toating 25mpg and near 400 horse stock. Ive rode in these trucks and Im thinking the new HP is rated on little 1-3" tall horses where the old motors are rated at full size horses(7-8 foot tall)? Maybee Ive had too many Barley pops but the new stuff seems lacking. I realize trucks are heavy but I remember old trucks with Big blocks(chevy ford mopar etc.) Is it just me? bench racing? Im 40 now so we never lined them up, but seat of the pants tells me old school is much more satisfyting.
