Re: '67 El Camino H/SA
I can take the delay even though it was estimated at 2 months. What really bugs me is the lack of concern/communication after the deal. I'm not one to make constant phone calls/inquiries...just would like some idea/time frame so plans can be made at least on my end. Already missed several races and I wanted some info so I could arrange time to have the truck painted. I finally said screw it and took the truck apart and carted it off to the paint shop. If they call anytime soon now about the trailer I could not pick it up as it is the only one with a gooseneck hitch that I own.
Probably not any concern to them, but a couple of friends who were interested in buying a trailer have taken notes of my experience thus far.

Re: '67 El Camino H/SA
I don't know on the cranking pressure currently. Have been swapping cams. The heads are milled, the block is decked. Supposed to be 9 1/2:1, open chamber FFFord heads. I didn't pick up as much in the 60, but in the quarter it was better than .1 and almost 2 mph.

Re: '67 El Camino H/SA
Dave, you're running a Cleveland though and milled or not the open chambers have slow flame propagation and poor mix. I would think that would add a new dimension into the whole thing compared to a smaller chamber chev.
Compared to a Windsor, the bigger chamber Cleveland liked more timing all through the rpm from what I remember too. For comparison sake, I built a 289 with 260 heads and it was quickest with 28*. Small efficient chamber required little advance (didn't breath worth squat even with the 1.78/1.48 valves put in) Would nose over around 6000 regardless of cam/carb/exh/etc but man it would go from idle to 5800 like a fuel motor! |

Re: '67 El Camino H/SA
I had an 11:1 351 Windsor in my car before I decided to try Stock. With the timing at 36 it slowed .2 on 110 Sunoco. I raced it @ 40. It had 215lbs cranking compression.

Re: '67 El Camino H/SA
Wow Dave, that's abnormal for a sbf. I'm assuming you were using 69-70 351W heads? I had a 2 4bbl 302 I built which liked 38* which seemed a lot, when I pulled it apart the pistons were washed clean around the circumference of the piston and the centre was black. I chalked it up to something I did wrong while porting and chamber work and that was why I needed 38. 40 though, that to me seems pretty high.
Course they all ain't the same are they? Lol! |

I have same set up. I make adjustment with my weight in deicers seat aka friend and some stuff in drivers seat and adjust to 0 preload. That gets it in ballpark and expand or contract right side as needed. |

Re: '67 El Camino H/SA
I did just that the other day while in the shop. I have yet to get back to the track to test it further...calling for rain and temps in the upper 40's for this weekend. It's about time for an engine swap and I may just retire it for the winter to concentrate on getting it ready for next spring.

Around the circumference? Can't say for sure but sounds like a Ring issue to me. Can I ask what fuel you were running that your sbf liked just 28*?

Re: '67 El Camino H/SA
Dave I was running 110-140 Av gas from the airport. You'd think more octane and slower flame front would want more but I just used what was available at the time and adjusted to its quickest. It is what it is I guess?
Chris, sorry for derailing the thread. Last edited by goinbroke2; 10-26-2017 at 11:37 AM. |
