Hey guys,
Wondering if roller rockers are worth it for a stock/good running 67 ford 289 2bbl. What will they do for the engine, can I expect any noticable improvement in a stock motor, and I thought the ratio for a SBF was 1.6. Appreciate your thoughts. Saw these on the bay for 60 bucks, though they might be worth a shot:

Up for bids is a BRAND NEW set of Pro-Comp 1.7 Ratio, 3/8" Steel Roller Tip Rocker Arms.

Fits Small Block Ford 289, 302, 351 Windsor SBF

Part# 0830203

Sportsman Steel Roller Tip Rockers are a definite improvement over stock rockers, Procomp steel rockers are made from 4340 heat-treated steel, and feature a longer slot design to eliminate stud interference.

4340 Steel Rocker Body
Includes lock nuts and slotted pivot balls
Adds up to 30 HP over stock or sportsman engines
Excellent replacement for stock or sportsman engines
Eliminates noise & slop associated with worn or high mileage rockers


Thanks.

Can't see them adding 30hp on a stocker...but you should see a little difference. Any reduction in friction in a motor is going to help.

At stock levels you'll see reduced friction that might be worth a couple hp and a bit more valvetrain reliability.

Your money is definitely spent better elsewhere as far as gains, but there is certainly no problem with reducing friction and adding a couple hp

Thanks guys, that's about what i figured.

Beware of new shiny very cheap performance parts on ebay. Make sure it's a name brand before investing your money.
