Hydroboost

Anyone use hydroboost from an express van
I seen the minivan ones have real short pushrod compared to the trucks

I picked up a low milage 99 3500 with L31 yesterday with the typical leaking intake these motors have

Re: Hydroboost

I'm trying to get the the local pick a part to look at hydro boost systems. Would love to find one with a short rod that might work just bolting it to the power boost bracket and then attaching to the assembly on the engine side of the firewall. It looks like it need to be somewhere around 4" or so from the mounting plate to the end of the clevis pin hole. I'll post my findings after I do my hunt.

I picked up two vans this week Express and a g20 with rebuilt front suspension waiting for me to find a 2 wheel drive frame
The Express has hydro and typical blown vortec intake

Re: Hydroboost

I just pulled one from a 95 suburban with a short pushrod. It looks like it will bolt up to my mc and work.
