Yes, then the “why to a 318, etc” questions, I get it though. It’s easy for me to spend someone else’s money!

Or, change the pistons out for forged, scout around for a 6-71, and… :)

lol! I’ll get the one in it out this week, send it off to get measured, who knows, the shop may have picked a decent one.

I’m often told I ask too many questions, over think things etc. but I think it’s as you mentioned, just make a plan. I’ve no issues changing midstream from what I started off with. Could be why it takes me so long to get going!!!!

Well now…I sent a message a bit ago to a fella who works for with Delta cams or Oregon cams. I don’t recall, but he’s a member on the board I normally go to. I’ve asked hom to build me a cam card on the cam I have, then I’ll go from there. If the juice isn’t worth the squeeze, I’ll just run...

I might add, in the first thread I came to realize why I wanted to do, wasn’t a decent approach. I made mention of asking for advice and am following it.

Not decked, squared and to 9.58. Right now I’m .095-.105 down.

Give me a well running and responsive engine is my expectations. My days of high winding etc, are long gone.

Well I don’t know what it is and if there’s a better choice available. It’s not big $$ to have it checked out, heck, it might be fine.

If you’ll go halves;). That’s not going to be in the budget. I’ll have the shop take the block to 9.58 and square, been reading through the head porting thread, pretty similar to SBC heads, a few more things to remove, but easy enough and is basically no cost. I wont take it as far as to where...

I guess the first order of business will be to send my cam out and have them basically provide a card for it. Run it past you folks and make a decision from there. As I mentioned before, all I recall was “like an RV grind” which is a subjective at best.

Pretty sure I mentioned it before, but early on when I was set straight on cams, was to use a modern grind vs 50 year old technology. I just brought up the LSA because he had mentioned it I don’t know or speak cam-ese so I ask questions and gather the replies.

I did, he said a 110 LSA seems to be a good compromise. Which leads back to why I decided to not go with the 340 cam via information posted here.

No I’m not, I started this thread and was soon told about newer/better grinds, LSA, etc. I just mentioned the Summit specs of it, and noted it was 114:)

Well let me ask this here, seems Mopar did like other manufacturers, in 71/72 the timing sets were 4-6 degrees retarded when installed straight up. I should get a degree wheel, but won’t know what I have in it now until I get more off of it. If my set is retarded, just get a 70? I guess, 318...

I looked on summit, the LSA in is 114. As I’ve been told in this forum, 106-110 is best for a low compression 318, to build cylinder pressure. Only vacuum I have will be for the distributor.

Regarding the gasket diameter volume, may have been because of my search brands, but all were 4.15(or close) hole diameter. I do recall a 4.080, but it had a “notice “ about using it. But I was mainly just looking to see what is available. But volume does make a difference, notice that a...

Let me add though, it may have been Mahle. When I search for gaskets I just use HGs I’ve used in the past, FelPro and Mahle. Just a creature of a habit.

The gasket showed up on Summit while looking for 318 head gaskets. Is said “marine”, which sent me down the rabbit hole of seeing if a marine head gasket can be used in a vehicle. That rabbit hole, displaced my thought and I didn’t save the link to it, tried over and over and over to find it...

Well, I used Wallace racing, with .080 down and a .032 compressed gasket, using 68cc, 8.24:1 I used 64cc heads, 8.51:1. So I suspect the closed chambered heads must be 62 cc, and that may be where the 8.6:1 number was for? .080 below deck at TDC holds with my engine, it’s .030 over, and...

Good deal gents. I have a 50 cc syringe in the tack room I can use to verify them. Also good info on the regrind of my cam. Thanks again. I’ll leave it up to them with the information I gather.

I thought this thread was locked as well:) I didn’t want to scroll back, but there was mention of ‘72 CR. I can assure you no way I’ll be at 8.6? I think it was SCR. With the .030 pistons it has now, 4 corner measurements sow .105-.095 with them at TDC. But that’s not off a centerlines, just...

Yes, in reading the thread, to be honest I have no comments on a lot that has been posted. The old “best to keep quiet…” rule, but hey, as was mentioned before, went to 10 pages plus. As I mentioned before, I listened, in the bench racing talk. I never participated or tried to add to what...

I know what VE is, but don’t believe I’ve heard of VP.

Oops, I meant “shorty header style CI exhaust manifolds”. Mine don’t go straight down, but have maybe 12-14 inches of length to them

I think maybe two differences between the Chevrolet and the Vette. One I’ll ask about, because I don’t really know. Does his have factory style short cast iron exhaust manifolds? One I do know about, no way the heads of the General were going to not let the Vette have a higher HO rating...

Well, for a higher winding BBC than mine was/is. It’s an LS5 from a 70 Vette. About all in and done at 5500. I can say it was coming on around 3/3.5. Up to then not a lot of difference than the factory cast iron intake. Now to add, I ran 3.07’s in the ‘57 at the time. It matched up well...

I am pretty sure I had the small spread bore holly on the SD I have. But I done recall the size of it, or the square bore one I have that I can’t recall why I have it. I’ll still hang onto the one I don’t use and the 302 SD intake, I have a 302 in a shed out back, just don’t have a need to use...

Well, a few reasons on the Streetmaster. One The small ports worked well in the days before the performer dual Plane was out. The second for the era I want this engine to look like, it’s a better fit. Another is since I lowered my original expectations and and thoughts on the engine, 5k max...

Sorry, hope you didn’t take offense, as that wasn’t my intention. There were some replies made by some I think just read my original post, skimmed through, missed some key items and commented. No matter. But I thought a bit of a background (maybe should have been my introduction post...
