Rapido marine engines

[ObjectCoder]

Good call Pete.....Here's what I found Port Side 462624 1979-85 1.94 Intake & 1.5 Exhaust.....Starboard 3998993 1968-76 1.72 Intake & 1.5 Exhaust

This info I got from Small Block Chevy Cylinder Head Identification

This not good and explains at least some of my issues yes? Now a question for you SB guru's what kinda of issues would this cause?

I wish I had known/thought to look at this last year.

Well I guess we'll find out just how well Raul stands behind his products now. I will give him a call tomorrow and see what he has to say.

I recently received a small block Chevy motor from Raul, I'm in California. We found numerous bent push rods and the "pre set" value lash was way out of wrack. Even with new push rods, and properly adjusted lash, it still has a small back-fire pop on deceleration every now and then. It simply can not be adjusted out. If Raul is mixing and matching heads, I wonder how many blocks and heads are not actual marine blocks? He doesn't require a core, so I'm betting most his blocks are automotive reconditioned with brass freeze plugs, etc, and so forth..

Re: Rapido marine engines

ObjectCoder, as already pointed out, you have resurrected a 3 year old thread. Please don't ignore the red banner at the bottom of the screen on threads more than 3 MONTHS old... As such, I have separated off your comment into a new thread of its own.

Now, to comment on your comment. Apart from the brass core plugs, cam profiles and the use of non-steel head gaskets, there is no difference between an automotive block and a marine block. Apart from those 3 differences, a marine block and an automotive block are indistinguishable... That's why most people who suffer a cracked block during winter have the option of getting a truck engine and just swapping all the marine fruit and veg onto it and being done with it...
