I have posted about putting a 302 in a 1975 4 wheel drive but decided to go forward with a 460. In looking for one I came across another truck with one in it also. Its a 1977 4 wheel drive very nice truck. So I got lucky there. I would like some advice on what some of you have done to your 460's performance wise. I am not trying to build a race truck but just a good strong all around setup. Thanks

 

Well were do i start? I quess the bottom end. I kept the stock crank i just polished the jurnels. The rods are stock just reconditioned. I went with .030" over flat topped forged pistons. And i decked the block till the pistons were at .005" in the hole or below deck surface. The heads are D2VE heads with bigger intake vavles and a moderate port and polish job on intake and exaust ports I had also port matched the intake and heads. I also went with a adjustable valve train but if you go with a hydraulic cam its not absolutly needed. My current compression ratio is about 9.5 to 1 The cam is a crane cams powermax 353941<TABLE border=1 cellSpacing=0 cellPadding=6 width=550 align=center><TBODY><TR><TD colSpan=2><TABLE border=0 cellSpacing=0 cellPadding=2 width="100%"><TBODY><TR><TD class=formTitlesLeft width="6%">Lift:</TD><TD class=formSubtitlesRight width="29%">Intake @Cam</TD><TD class=formEntries width="7%">3027</TD><TD class=formSubtitlesRight width="10%">@Valve</TD><TD class=formEntries width="7%">518</TD><TD class=formtext vAlign=top rowSpan=3 width="28%">All Lifts are based

I went with a edelbrock performer intake. A holly 750 cfm hp series carb. K&N air cleaner and a set of fender well exit headers from L&L.When i drove the truck daily i wanted the lower compression to run pump gas. Now that its a show vehicle im going all out. I am rebuilding a set Dove heads with all the same goodies. it should take it to about 10.5 -11 to 1 compression. Keep in mind it is a 5500lbs vehicle if you go to radical with the cam you will loose bottom end. The cam listed above had givin me the best of both worlds. You want something to give you good off idle torque and pulls strong up to 5500rpm. Horse power is adictive

 

Gus11208 what transmission are you running?

 

I've got two dentsides and both have 460's in their future.

I have also acquired two complete 460 engines, as well as some parts.

I've got the cylinder heads; One engine will have D0VE heads and the other will have C9VE. (There's basically no difference and these are regarded as being very desirable heads.)

According to my research the best intake manifold for the 460 is the Weiand Stealth 8012. I have two of those. One I got on ebay and the other on Craigslist.

I'm leaning toward the Summit 3501 cam.

I've also got two Holley 750 carburetors. I chose the ones with electric chokes and vacuum secondaries.

I fully realize I'll give up some performance, but my plan is to have compression no more than 9:1 so I can use 87 octane fuel. The C9VE and D0VE heads have smaller combustion chambers, so I will need to use thicker head gaskets to get the compression ratio where I want it.

I also realize that headers will make the engines breathe and run better, but my experience with headers has been less than satisfactory, so I'll be using factory exhaust manifolds.

 

69 Lincoln Block, stock bottom end, 280 Comp Magnum cam, Hyperputic 10.5-1 pistons, Comp roller tip rockers, Edelbrock heads, Edelbrock Performer RPM Intake, 750 Holley manual choke. I run 93 octane (alot of 93 octane).
