Camshaft


I have a freshened up 1965  283 engine. Motor is standard bore, original power pack heads(freshened up) dual plane intake and small edelbrock carb. This motor is bone stock. What is a good cam to put in this thing to possibly wake it up.

I have had good luck with the Mellings MTC-1, 204/214 dur .420/.443 lift, nothing raunchy but gives a nice burble out the exhaust and stretches the rev range a bit more than stock. Coupled with a TH350 rather than powerglide, it really wakes up. Had this combo in my 65 SS, most would not believe it was "only" a 283.

I am NOT a cam expert!

But ask an expert if the Comp Cams High Energy 252H is a good fit?

.425 .425 206 @.50 110 lsa 

800 - 4800 rpm

 You could experiment with 1:6 rockers too maybe??


You could go with Corvette 2.5 inch rams horns and 2.5 dual exhaust too!

keep the stock look but let it breath a little better!

I've never used a Comp Cam but I've used Melling a number of times as Dan suggested and been happy with them.

Good info. here as I'm wanting to keep my 283, but pep it up a bit.

Not all of us need to over compensate with 427s!winkbiggrin

 Yeah, I've come to realize that not everyone in this hobby makes the best decisions like I do...

But back to the topic, one thing to keep in mind it's certainly easy to over cam a 283, especially if it's in front of an automatic.

Something else certain 305 heads work better??

so Ive read I have no personal experience 

but they may be a cheap upgrade and you could pocket port them yourself 

just another idea for you

all these little things added together should add nice street power

again I am NOT an engine expert

I have also heard about using 305 heads. I am no expert but I have heard that the 305 has smaller combustion chambers for a boost in compression, hardened exhaust valve seats and the mounting holes in the heads for more options to mount engine driven accessories.

Long video with lots of fluff but also some great content mixed in with it. I think he's reaffirming something we're hearing a lot of lately.
