Default 5 hp Briggs dyno cam long lifters

I got a 5 hp Briggs recently and impulsively bought a dyno cam off of eBay for cheap... and nothing else. Now I know I need at least longer lifters. I think stock is 1.600" and there's a .1" gap in between the lifters and valves. I've only seen one set of long lifters for sale on a website that I don't trust for to much $. Any suggestions?

well you can adjust the valve gap instead, can't you?

arcracing.com sells +.1" lifters however as far as I know
And they're indeed a very trustworthy site to use.. (should be roundabout 25 bucks or such...)
I am not aware of anyone claiming to have ever had a problem with them.
And as the manufacturer of nearly all the billet parts we know..
there's no reason to assume they're trying to scam or cheat

Are you sure?? 0.1" of valve lash?
If so, that is a ton of valve lash. What makes you think you need longer lifters?
Your block may also need to be welded at the lifter bore area so you don't destroy a block with an aggressive cam.
You NEED to know what the numbers are on the cam(lift, duration, geartooth count just in case), and send the numbers in to Dyno Cams so they can tell you what cam you have, what fuel it's set up for(some are set up for alcohol), and what needs to be done to ensure you don't wreck your engine.
Just for future reference, don't buy an unknown cam unless you're willing to build a very high horsepower engine. Usually the different parts you need kinda depend on your cam
Dyno Cams is a very trustworthy company, they've been around for a while to boot!
Oh, and

Can we get a pic of the engine, so we know if it's a flathead of an ohv?

It's a flathead and the plan was to "supercharge" it with the smog pump off of my Toyota but that will have to wait. As you can see if my pictures uploaded right that the dyno cam has a skinnier base or heal than the stock cam. Really Shoulda known that It wasn't just going to be plug and play but here I am.

This is my go to website for flathead stuff, the way to order is a bit archaic, but they are good people over there.

Sweet! Thanks Grant! I had seen that website but didn't trust them(I'm naturally suspicious), but it's good to know they can be trusted.


A steel bore, dual bearing block is $300!!!
