# 4 heads from '67 330 along with 330 crank shaft even block put valve rotators and hardened seats put the W-31 valves depending what your going to use it for. But I'd go W-31 camshaft 308 duration same as W-30 automatic balance and aline hone block & some head work 400+ h.p. with good tune and few tricks 10:25:1 pistons. That is s nice looking unit I had quite a few of them...three on the road for a couple years '64. '67. '70. Plus many other parts cars . The '64 had the '67. 330 built. 400+ h.p. 4-speed 3:90:1 posi The '67. Had. '66 425 built. 500+ h.p. turbo 400 automatic 3400 stall converter reverse pattern manual valve body 4:56:1 posi The '70 W-30 automatic put the 328 duration W-30 stick grind camshaft,. 3:90:1 posi. Headers, Holly carb and reworked the heads slightly with B&M trany rebuild street/strip running drags at 12:60's @. 102 m.p.h I did not go overboard on the "F" Heads to much just help them out a little... Yours sounds really good .. what camshaft you running I find that olds run very well with there factory parts I played with a lot of different cams and weighting out the pros and cons for my '66 & '67 motor 's factory work well the big block had to have the camshaft custom ground because of the 45 degree bank angle most Olds are 39 degree that was 328 duration with Edelbrock Torker intake manifold single plane it loaded up a lot waiting at the lights had to clear her out in neutral not much for street driving same with 330 but at least that was 4-gear I let those two go years ago should have kept them but I still have the '70 W-30 out in the barn... Take care of that one you got she looks good..
FI is a great option and I have been seriously considering it lately. It makes it much better at starting and the self tuning features on some of them are really good for power. I don’t think it’s too much work but you may have to redo your fuel lines and get a fuel pump. Depending on how much pressure you run some of the high flow pumps can collapse old fuel tanks but I wouldn’t think that’s a problem. The work and price is probably worth it in my opinion.
@@DawsonSiebert I went with the Holley Sniper kit with timing control on my mildly modified 1974 350 Olds and the tuning capabilities are amazing. Used their external inline pump, drilled the sending unit assembly for a new 3/8" feed line, and used the old factory fuel line as the return.
We the stock pistons, the heads are the original heads but we had them planed to bump the compression and new seals and heavier springs. In all it’s a 9.5 to 1 compression ratio I believe
What size breathers do you have in the valve covers? From what I’ve measured, the holes in either cover are not standard 1”, 1.5” etc like most breathers.
Hughes 2800 rpm stall. It was recommended with the camshaft that we ran. So far it has worked well for regular and spirited driving, if you are going for a fully race orientated build, I would go higher
If your trany is 400 turbo check wreckers for a '66 to '67 400 turbo from Buick or Olds grab that as well as same year same cars 2-speed getaway from a small block motor they both used a switch pitch tork converter you put the smaller 2-speed converter into toe 400 turbo switch pitch pump they will fit and that pump will also fit newer 400's as well.. you will have a low stall of about 2,200 & a high stall of about 3,000 r.p.m. just mount a little toggle switch on your shifter that's what I did for my '66 425c.i. but being a big block I got more stall about 3400 once I got going and the rpm got up I switch into low stall so it would not slip as much... Take- care...
