| I want to bolt on a set of ratio rockers on my 67 bus. I rebuilt the trans. with a 3:88 and .077 4th but lost pulling power! I'm not sure which to use, the 1.25's or 1.4's. I have a set of ratios, I belieive they are 1.4's but when I installed them and checked lift on #1 exhaust it "stacked" the valve springs where I couldn't get a .06 feeler gauge between the springs! These rockers had the adjusters on the push rod end and cupped ends on the push rods. The push rods I got with these rockers are shorter than my stock aluminum push rods so I can't figure out why my #1 exhaust valve springs "stacked". I will probably order a new set from SCAT but I'm not sure whether to buy 1.25's or 1.4's and if I buy 1.4's, will they come with the correct push rods or will I have to cut a set to fit. Anyone out there with advice and experience in using the ratio rockers and how much diffence they make on a stock engine with stock cam will be greatly appreciated. I'd like to use the 1'4's to get more power but are they worth it or should I use 1.25's and what about push rods? Thanks for any experienced advice! |

| Before you buy anything--Get a copy of a March 1998 Hot VW`s magazine--There is an article on increase HP on a stock 1600 including ratio rockers, it will really help. I have a Scat Zero Mile 1600 in a 67 type II and and did the improvements called out in the article and it really made a jump in performance.----Bill |

| You might be disappointed to find that ratio rockers only add significant power at the higher rpms...4000-6000. Not much use unless you've got the rest of the parts: HD valve springs, etc. to go with it. |

| try looking up some information before making a choice on rocker arm ratios.here is a good source: www.geneberg.com. Go the valve train section.in the magazine pg 63 under technical information. there are certain cams designed for ratio rockers only. its the way they grind them. try'n to help!! no such thing as (just bolt them on!) |

| you only want to put 1.25 rockers on unless cam was designed for more. I put some on a stock 1600 d/p. and was suprised at the extra kick above 2500RPMs lost a little on the very bottom but felt driveability was much nicier with the extra kick,bus was a complete 69WESTY gas milege stayed within a couple of miles a gallon. THANKS TOM |
