I have a Blueprint 350 in my 1953 Chevy Sport Coupe. It is the 310 HP version. If I had it to do over I would go for less HP and a smoother running engine. This particular engine has a rather radical sounding cam and the whole car shakes when it runs. If that's what you're after then go for it. I wanted a smooth running engine with a very mild cam. I have considered detuning it after the warranty period by putting an RV cam in it. I also had a problem with detonation unless I ran a minimum of 91 octane gas.

hmmm. think their 350 version would be a little nicer at idle etc? they list it to run on 87 pump gas.

I've been told and have read that their 350 has a nice cam and that it runs smooth . I guess no one here has an dealings with Five Star Engines .

I would AVOID MOST EBAY engine deals ,
As I hear frequent complaints, and deal with a engine rebuilder company that supplies a warrantee
why not call a few local chevy dealer parts counters and JEGS and SUMMIT also

IF YOU CAN,T SMOKE THE TIRES AT WILL,FROM A 60 MPH ROLLING START YOUR ENGINE NEEDS MORE WORK!!"!
IF YOU CAN , YOU NEED BETTER TIRES AND YOUR SUSPENSION NEEDS MORE WORK!!

Unless I absolutely cannot find it elsewhere (like synchros/gear sets for old Hondas), ebay is the last resort for anything automotive related. Unless it's for generic floor mats, etc.

Even when shipping is factored in, the outrageous prices compared to places like RA is enough to keep me away.

We recently installed a GM 350 crate motor in a 75 Corvette and have been pleased so far. No issues with installation or break-in. Very mild cam, smooth idle. I believe it was rated at 308 hp. Picked it up at the local Chevy dealer so no shipping involved.

I would never buy an engine off eBay. If I was to buy a complete engine, it would be from GM or a local speed shop that I knew and trusted.

Do you mean the Blueprint 410hp version maybe? They don't make any 310hp small blocks. Even the 410hp doesn't have a very radical cam. A slight lump at idle is all it should have.

This engine might not be offered any longer. It was purchased in 2016 and installed by a rod shop. It was advertised as 310 HP and came with a Holley 600 and high performance intake. The HEI ignition advance was closed off. I didn't like that either.

Have you inquired with some local machine shops/engine rebuilders?

A 310hp engine definitely shouldn't have a lumping idle unless they mismatched the parts. That's "RV cam" territory.

I have a good friend that runs Blueprint engines exclusively in his builds. He has bought so many of them that they called him a while back to tell him of an engine they had on sale.

He bought it, and started another build just to have a place to put the engine!! lol

He has at least one still in the crate in his shop. I asked him if he wanted to get rid of it, and his answer was that if he didn't want it, he wouldn't have bought it. Made sense to me. haha.

He has a few small blocks. One is a 383 with a roots blower on it.

Mostly he is runnings LS sytle engines now.

All of them with forced induction of some kind.

All I can say is that he loves them.

I looked up the engine (BP3501CTC1) on their website. The engine I bought in 2016 is now listed at 365 HP. Specs say I can use 87 Octane gas but I get terrible spark knock unless I use 91+.

Setting up the ignition curves and vacuum advance correctly should handle a lot of that pinging.

Lets hope the engine builder knows about proper quench, and adhered to it, as well.

GreatNorthWoods:
Any engine builder or hot rod shop that blocks off centrifugal or vacuum advance on a mild street engine has no idea what they're doing. There is so much info out there now on how to properly set up ignition curves and vacuum advance there is simply no reason to run either locked out on the street. I'm guessing the installer blocked off the advance?

As for the cam shaking your car, that shouldn't be even with a radical cam. Looking at the engine specs that cam should purr like a kitten with just a little chop. I'm running a Comp XR294HR in my smallblock that has a VERY noticeable chop. Even with that, it' doesn't rock the whole car in or out of gear with my relatively tight converter. That said I suspect your issues stem more from an improperly tuned engine than the cam size. Does it smell really rich at idle and get poor fuel mileage as well?

The shop tried retarding the timing so that the engine would run on 87 but performance fell off so badly they had to bump it back up. The blocked off distributor advance came that way from Blueprint. I was not a fan of that and considered unblocking it after the warranty period.

No rich smell when the engine is running and fuel mileage is about 13 MPG. I have a higher than stock stall converter.

Sounds like the carb is set up ok-ish, but will need to be retuned after getting your timing straightened out. How is your throttle response? Does it rev nice and snappy? You really should do better than 13mpg with that engine and a 700R4. I'm doing 12mpg with a gang more cam and a Th350 with a 3.70 rear gear and 2400 stall on a 29" tire.

I'd be willing to bet setting your initial timing to 10 to 14 degrees (you likely won't need more with your combo), dialing in 20 degrees of mechanical advance with a light silver/blue or blue/blue spring combo, and hooking up vacuum advance to a full manifold vacuum source (while limiting the total vacuum advance to 10* with a limiter plate from Crane or a custom fabbed piece) will make a world of difference for you. The reason your engine chugs so much and shakes your car is because it's struggling to idle.

IgnitionMan posted above, and let me tell you his advice on ignition timing is invaluable. He helped me get my timing issues sorted out years ago.

Bought in 2016 it's out of warranty now so might as well work on it.

Throttle response is very good. Much of my performance issue is rear end ratio. I'm running a 3.08 gear and should be running something around 3.42 or lower...just haven't gotten that far yet. I plan to change it eventually. Thanks for the timing advice.

I agree, Ignition Man is the professor of ignition set ups! He helped me sort out a engine years ago also! So listen to him!
