I've got a 327 block that I'll have overbored 0.030. I have remanned double-hump 2.02 heads. I want to make a high compression ( 11.0 or 12.0) and low-end torque. I'll be putting into a 55 Chev with MFI (Hilborns). I want a rotating assembly that fulfills the above requirements, uses H-beam rods and is not real costly (I'd like to spend $1K or less on the entire RA). As for a cam - I wanted to find an Isky 505 Magnum to keep with a real nostalgic theme but haven't found one in the past year so I'll give in and look for a commercially available one. Any suggestions here??? Thanks, JohnK
Well, I just called Summit to get a price. I now know why there have been no replies to my post yet. For a 0.030 over RA I was quoted $2700! A little off of my "under $1K" requirement! I'm going to call Jeg's next and see what they say, then an engine guy in town here to get a couple comparisons. I'll keep you posted on my quest... Looks likeI may have to loose up the ol' purse strings a bit...
For pump gas use, is your compression a little high? I thought 9 or 10 to one was about the max on 93 octane pump gas.
If you want cheap get the crank out of a 307, if you are small journal you'll have to have the journals turned. Knife edge, polish yourself. Gun drilling and an balancing will run you around 2-300 dollars. Another 100 or so for turning. Buy aftermarket rods and pistons (prior to balancing). You'll still only have a 327 but you should come pretty close to your grand. If torque is what you're after get a 350 crank you can still find them in steel. Do the same as above. That'll net you 355 cubes. Contact Raven, he's got a stack of vintage racing cams. Some Iskys, an M/T etc. From mild to wild. maybe if he's in a good mood he'll hook you up. Grins -- Benno
Update.... I called Jeg's. They told me they didn't have ANY RAs for a 327 (331). Their suggestions was to bore/stroke it to 350/383 and buy a RA for that size! Benno - thanks for the ideas! I'll be sure to contact Raven.
It's not so much that I want "to go cheap" but I am on a budget. I have only so much money to work with but I want to build a good, safe, hi power motor. If it means I need to save more and wait longer, so be it.
Benno - This is a '69 block so it's a large journal. I was thinking about your suggestion of using a 307 or 350 crank. Are both these cranks LJ? I talked to a guy last night who said the $2700 price wasn't out of line for a 327 RA 30 over with forged alum pistons. Like I said, I just want to build a good, stout motor w/o having to sell the kids... Tom - I guess my desired CR is alittle ambitious... how about 10:1???
