CAMSHAFT FOR 350 (Idle to 4500 rpm)

What I have is a .030 over 350 (355) with flat top pistons and 194 heads , casting 462624 . I have torn it down to re-gasket everything . I have the heads back on and am now thinking this would be a good time to change the camshaft . I cruise the 30 mi McCorkle avenue mostly (speed limit 40 & 50)with my T-bucket or the blacktop backroads , so am looking for a cam to give me the best performance and driveability and fuel economy in the idle to 4500 rpm range . The torque stalled at 1800 with the 305 . I am thinking RV camshaft . I just got off the phone with Advance and they have a stock cam for $34.99 or they can order an RV cam 800 to 3800 rpm range for $62.99. Any real advantage in using the RV cam over the stock cam ?

I would use the edelbrock performer plus cam or the summit eqivilent. It has .204 intake and .214 exhaust duration @.050. It`s ideal for what your looking to do. Summit racing carries the same cam with lifters for a lot less.

Good cam for the application, IMHO.

Between 2000 and 5000 RPM, it never drops below 325 ft/lbs. The TQ peaks around 3500-4000 RPM @ 377 ft/lbs and makes 310 HP peak.

This is w/an EPS intake and 600 CFM 1406 (calibrated for economy version of the 1405) along w/Performer heads. The Performer heads have 170 cc runners and 2.02 x 1.60 valves in them, so will have higher peak power at a slightly higher RPM than your heads. You might see an increase in torque down low w/your heads, but less up top in other words.

Now, that cam and a set of Vortec heads...

When I rebuilt my stock 79 350 I put in a Performer Plus cam kit, performer intake manifold, and 1405 carb. I couldn't be happier.

My truck spends most of it's time between idle and 3500 rpm. Throttle response is great with much better seat of the pants feel than when it was stock. My biggest surprise is how smooth the engine runs. Mileage is about the same as stock with the Qjet. However, I haven't got over the new power, so I spend much more time than normal at 3/4 or full throttle, so I'm sure there's another couple mpg to be had when I get over the WOW factor.

The only thing I have left to do is top it off with their performer heads. Hopefully that won't be too long coming.

Thanks for all the advice

Boy I am sure impressed with all the knowledge out there . I hate to disapoint but I just went with a stock cam from Advance Auto . It mics out to have a .274 lift . The lopey cam I took out miced to have a .280 lift with a LOT of duration . The lobes look so wide they look like a roller cam . I noticed exhaust up in the intake runners which I guess is to be expected with a lot of overlap . Am I correct in guessing HP in the 275 to 300 range with what I have now ?

Melling MTC-1 would have been another good choice.

I was just going by an engine I had bought way back in the early 70's that came out of a '70 Monte Carlo . It was a stock 350 factory rated at 300 hp. I assumed it had flat top pistons with 1.94 heads . But then you know what they say about ***-
u-me . LOL

Your engine would be on par w/the "300 HP" engine from the M/C- the engines from then were measured differently than they were later on. They had more generous SAE correction factors for air temp/density, ran less (or no) accessories, the engine rearward exhaust systems were deleted in some or most cases, and this amounted to a higher reported HP rating.

Along about '73, the SAE changed their standards, resulting in a more "real world" (read: lower)
HP rating.

Thanks for the input cobalt 327 . That's really all the engine I was hoping for. The M/C engine ran good in my '67 Imp. SS which weighed 3615 and didn't have headers . In my 1840 lb T-bucket with headers and 3" header mufflers and the only accessory being an alternator it ought to be bad enough to scare me . It is ready to go in. I quit for the day . Real feel is over 100 deg . Shower and then recliner time .
