I am swapping out my stock 350cid with a 383cid 405hp/450 torque from Blueprint engines (Summit Racing) and am running a new 700R4 from Monster Trans. I have a couple questions...Has anyone heard anything bad about Blueprint Engines? And when I install the motor, can I use my stock radiator if I have it cleaned, rodded and checked? I don't want to run hot if I need a bigger radiator. Can I use my stock flex plate on the engine swap from my stock engine to a crate engine? What is recommended?

Thanks, Brad

stock radiator in good condition is fine..I have no overheating issues with 525HP and the stock radiator ....no on the flexplate ..383 requires a weighted plate not a neutral plate ..didn t your new motor come with one? or has it not arrived yet ?Blueprint can provide you with the proper flexplate ... they have a very good warranty , one of our members had a failure after warranty expired, and they still made it good.

It comes with a harmonic balancer but no flexplate. I will talk to them and get the right one. Thanks.

Be sure and tell them what trans you're using= the 700 convertor bolt pattern is a little different than a 350/400. Like just enough the bolts won't fit. Some flexplates are drilled for both. But it's certainly a PITA to find out AFTER you get the trans all bolted in.

Brad, you'll also need a set of 3.73's in the rear to go along with your high performance 383" engine. Fish can help you............

OK, guys, I am back!! I installed my new Blueprint crate motor (Dyno'd 417hp) last night and ready to install my Monster Tranny 700R4 tonight (with my new driveshaft). I would like to know what is a good radiator setup and thermostat setting to go with? Go back with original fan, electric fans, aluminum radiator? :thumbsup3:

Not sure how far you want to go with it, but I went with Dewitts aluminum radiator, dual spal fans, 160 thermostat, did a serpentine conversion from an 89' Firebird and used an Edelbrock Victor Jr reverse flow waterpump, and a March underdrive pulley set.

 

[whiteonred80]

Holy cow batman!!! Now that is nice!! I may start by using the radiator setup, and I like the 160 thermostat. :sm_party:

if you need a radiator, alum is the way to go.. your stock fan w/shroud will provide adequate cooling,but if you go electric, go big on cfm ..

 

[whiteonred80]

I am transferring everything from my old carb to the new and I have a wire from my automatic choke. I guess I don't need this wire because it doesn't look like an auto choke on the new one. There are a lot of changes from my original motor to this 1986 and up style. I hope I don't miss anything. I brought over my throttle cable holder, cruise control and the parts for my detent cable. I hope I get the detent cable on right, I hear horror stories about that.

 

[whiteonred80]

I am also going with new parts for the starter, alternator, power steering pump, oil sending unit, and temperature sensor. Any other suggestions? Of course, new belts and hoses, thermostat housing and thermostat (160F ???).
Does the stock fan make too much noise? I hear people say that but I never heard it or it never bothered me. I think I will reuse it and go with a new aluminum radiator. How many passes should it have? 2 or 3?

on the 700r4 its actually a Throttle Valve cable..it needs to be adjusted so that it is pulled all the way out at wide open throttle

I have installed the new Blueprint engine and now working to get my accessories back on. I am having issues with the pulleys lining up and I even had to purchase a short nosed water pump. My pulleys still don’t line up. Do you have any clue why this is? Should I install a serpentine belt/ pulley system since the block is a 1986 or newer? If I do, doesn’t it take a reverse flow water pump? And maybe a different style power steering pump? Any info would be helpful. Thanks.

which one doesn t line up? or is it all? 80 or 86 ,The block is no different in the front. ALL Your original 1980 pulleys should still work with a Corvette short waterpump with 3/4 inch shaft.. is your Harmonic Balancer all the way in?

If your damper isn't all the way on it's very possible the small Woodruff key has rolled and if it has the damper will have to be removed and the key re-positioned. With your original pulleys mounted on the water pump the rear of the pulleys should exactly line up with the front of your damper..................

It measures the same distance from the timing cover as on the old motor. I am assuming it is all the way in. Send me a pic of your pulleys to make sure I am installing the same as I took off, I believe I am.

Your original water pump was a short nose so why did you have to buy another one? During this engine swap you needed to use your same pulleys along with everything else so what have you changed?

If you re using all the old pulleys and a Short pump, and the Balancer is the only thing new, and you say its all they way in, then maybe its not the same thickness as original

Question about the fuel pump and lines... I have 2 lines coming from the tank, I assume one is a return or vapor line and I only have one port in my fuel pump ("IN") and one line ("OUT") going to the carb. What do I need to do?

 

[c3speed]

That is a return line that you don't need. Just cap it. What was the problem with your pulleys?
