Re: Anyone got a picture of an SVO 351C head with Jesels?
Have you tried calling Jesel ? They just helped me figure out an ancient set of their rockers about 2 weeks ago. I did call them, they were nice enough, but basically said, " Pin or strap if you want, back then we didn't bother because springs were weaker and lift was lower " I did learn ...

Re: Anyone got a picture of an SVO 351C head with Jesels?
End result, I pinned all 16, it was quick and easy once I got the procedure down. I looked at strapping across the rocker bolts, but they recess slightly into the shaft and I would have had OD washers that fit the recess, I looked at TiG for the center ones, but the gap between stands was big enough...

Re: Offshore head and intake ID
Awesome, thanks for that. I have been trying to figure it out I think what I have here is a 331 crank with SCAT rods and DSS pistons for a 347. I'll do some additional measuring this week. That was piston part number and measuring stroke with dial calipers from the deck. If I can reuse the rods and ...

Re: Offshore head and intake ID
The plot thickens,,. They seem to be Speedmaster or Procomp, same head I understand just how old they are determines name However, looks like DSS pistons with double intake valve reliefs for TW and regular heads, maybe SCAT I-beams, but the odd thing is a cast crank with HM on one throw and B on the...

Re: Offshore head and intake ID
If the intake side of those heads can do 250 cfm@.550” then with that cid you should easily make 450 Hp. Each intake runner needs to flow that or a tad more also. I have sources that say 209 cfm at .600 too, so we'll see. I'd like to see more and not need to pull on the port as hard with overlap, b...

Re: Offshore head and intake ID
Well Bill, whatever the reason is, he didn't get any blueprinting info and doesn't trust it, so I am going inside anyway. I doubt running it would be much more than a waste of dyno time, assuming it doesn't spin a bearing or shake itself to death. Hell, it's been on a stand in the corner of my shop...

Re: Anyone got a picture of an SVO 351C head with Jesels?
Thanks for the response, what keeps the last rocker on each of the head from rotating on yours? I considered pinning but don't really have a good option for that.

Re: Anyone got a picture of an SVO 351C head with Jesels?
Well, been searching the internet and it looks like they just hang out the the last valve on each end of the heads without something to keep it in place. Nothing there to keep it from rotating, very odd. Found a T&D did the same thing Seems like if they shaped the stands to link to each intake a...

Anyone got a picture of an SVO 351C head with Jesels?
A customer had an engine disassembled at another shop and brought it to me. As far as I can tell, the last rocker stand on the end of each head isn't positively located with a partner like the others B351 SVO heads with Jesel shaft rockers. Supposedly ran with these parts (although it certainly need...

Re: Superflow 110 For Sale
Sorry to look like a lead and go quiet, I think that will be a bit small for me. Not that I need a huge one, but would like to pull a little harder on the port than the 110s do.

Wanted - Flowbench
I am looking for a flowbench equipped with or able to be equipped with digital measurement. Does't have to be a big one, looking to baseline sub 3500 cfms heads only, not a head porter. Prefer single phase 220V or 120V Would prefer a days drive from Omaha NE if a big one, or if able to readily ship,...

Did this sell? Looking for a slightly bigger one, but beggars can't be choosers
