The shortblock was built sveral years ago and consists of the following parts: '70 440 block .030 TRW L2295 pistons (yes, boat anchors, but what we have) Eagle H-beams Mellings std volume pump .010/.010 forged crank ARP main studs balanced rotating assembly Heads are Edelbrock 84cc Comp Cams 1.5 roller rockers Will this following cam be a good choice for a fair weather cruiser? Car is a 4-spd with 3.55 suregrip. It's an old stock Engle HL26 solid lifter grind. Found these specs on the web: 254* Dur. @ .050" and .513" lift with 1.5 rockers

It should be good cam for a mid to high 11 second time slip, if he's not fussy and doesn't want a stock idle it'll work. If he really just wants a crusier I'd go smaller. Any idea on the LSA? I'm assuming 108. Last edited by GTX MATT; 04/14/14 05:26 PM. Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

The gears are the one thing he won't change out. He likes to be a freeway flyer According to the second response from Chris at Engle, the LSA is 108 or 110. This is the first response from Engle tech: Hi, that is a big block chevy grind . It is .252� duration at .050�.342� cam lift .292� running duration .513�lift The lash is .018�int .020�ex cold for Iron heads Chris Last edited by 70440+6bbl; 04/14/14 06:57 PM.

It has a nice little lope to it, but drives great. Get a little heavy footed and it wakes up real nice. 2014 Ram 1500 Pentastar V6 1966 Fury II 4 door

From what I have read here, seems they don't make nearly the advertised cr. My '71 GTXs 440 has the same pistons and with the original 346 heads (done by Valley Head Service in CA, years ago) and stamped 87cc, along with a Racer Brown ssh-25 cam, I didn't really have any detonation issues running 93 octane, unless I lugged it up a hill in fourth.

I'd plug all the specs into Kieth Blacks calculator & see what SCR you have & post the number here. You said you wanted a mild cruiser so I'd listen to what the cam guys who have already posted here have said & go with something mild(er) live every 24 hour block of time like it's your last day on earth

As for compression You could always go w/ a cometic gasket. This motor has .057 gaskets. I'm also running a comp cams 588 solid roller. [IMG]http://i66.tinypic.com/pui5j.jpg[/IMG] Coming soon!!!!

Regardless of the cam I hope the stock valve notches have been recut.As built they are way small and you will have issues in the outside corners of the cuts.That will limit cam choice.I have used them many times,with 86 cc heads and no milling of the block could be as low as 10.3. With 79cc heads and .000 deck they are easily can be 13-1. Cam wise,I have had great success with the Voodoo line.60304 would be a very good choice. Leave the gun.......take the Cannoli's....Mike

The heads where 906s, milled about 020 with Manley 214 pro flows. That motor was built 30 years ago so I'm a little fuzy the the exact specs. Oh and with that 4spd, if you put tires that will allow you to hook 'n book, you'll bust that 8.75

The block only had a clean-up cut.

And, he plans on a Dana soon

Except the big cam may help in dealing with high CR and avoiding detonation. Agree as others have posted, figuring the "real" CR and PV clearances matters a lot.
