Re: My experience with Blueprint engines

Nope, No more wisdom.
You checked everything and it is all still as stated above,,,, It's probably something simple that has been over looked,,,
How is the Power valve? I think that carb has a blow out protecter, but just in case it failed, you might check it too.

Re: My experience with Blueprint engines

I want to close the loop on my specific Blueprint engine tuning journey.

My problem was my carb and my timing.

FWIW--Here are my current overall specs:
383 Blueprint stroker motor
Holley 4160 750 CFM carb
700R4 trans with 3,000 stall 9.5" torque converter
Moser 3.73 posi rear
MSD 8360 distributor

First, Blueprint customer service was an A+. The lead tech at Blueprint has called me at home twice to check up on my motor and offer advice. He also asked me to call him back to keep him informed. First class service.

As for the motor, I finally gave up after 18 months of struggling to get it to run and turned it over to a local mechanic known for doing good work. The car now runs fantastic and feels like I gained 150Hp+.

I am experiencing some traction problems though--I gave it 3/4 throttle at 30 MPH and the tires broke loose and the car went sideways with the tires screaming and smoking...I guess I need better tires than the T/A radials that are on it.

I bought a new torque convertor from RevMax, thinking that would solve my problem. I was running an 1800 stall convertor in my 700R4 and upgraded to a 9.5" 3,000 stall convertor. This was not the source of the whole problem (but the 1800 stall torque convertor is now for sale)

Here is what he did:
--Swapped my Holley 670 CFM Street Avenger for a Holley 4160 750 CFM that he had tuned for use on his own race car. He had heavily modded the 4160 and then spent a few hours tuning it for my car. He enlarged the air bleeds and a whole bunch of other things that I did not completely understand.

-Unhooked the vacuum advance completely.

-Recurved my MSD 8360 distributor to get the timing in earlier.

-Set my total timing to 36 degrees. My initial is at 22 degrees.

And the car idles very well, the sound of the exhaust has completely changed and it starts immediately.

The price for all the tuning work plus I kept his carb was $275. I consider that a really good deal for all the work he put into it. (the price to swap the torque convertor was another $350).

Comments on this set-up are welcome.

Thanks to TC for walking me through this and thanks to Andrew and Ken at Blueprint for their oustanding customer service.

Re: My experience with Blueprint engines

Hey there! I've been waiting for this post to come back around again, really glad that you see the value in seeing it through.

I have a question... is that initial timing figure correct? Looks very unusual to me.

thanks!

Re: My experience with Blueprint engines

Yes, the initial is not unusual. Many performance cams like and need more intial than the weak 8 degrees before TDC. You have to change the amount of mechanical advance in the distributor to 12-14 degrees to run that amount of initial. It's the modern way to time an engine.

Re: My experience with Blueprint engines

Sorry I still don't follow. I'm not doubting that this setup is working out well. But I am trying to better understand a circumstance where this approach can be tried. Most small blocks run around 12-14 initial and moderately aggressive cams aren't new. The cam specs in my signature are for the 405 HP Blueprint Engine, his is either this one or the 430HP. So that cam might have a few extra degrees in it but I'd still call mine only "moderately" aggressive than stock. I'm at 12, per Blueprint.

Re: My experience with Blueprint engines

Brian,

The 22 initial is correct.

the motor remains the exact spec that came from blueprint.

I would have thought that amount of timing as too much but the car runs great and I have a lot of trust in this mechanic. He has raced and driven F-bodies and Cobras for 40+ years.

Re: My experience with Blueprint engines

Does the 383 require a small base circle cam? I believe thats what they told me when asked years ago. I'm wanting to buy the 383 forged block but I heard a small base circle cam wasn't the best choice.

Re: My experience with Blueprint engines

Nevermind. Blueprint told me they use remanafactured blocks instead of new, and they do require a small base circle cam unlike the ZZ383 block that is new comes with dampner and flex plate and has been clearanced for a standard circle cam for a few hundred more.

Re: My experience with Blueprint engines

On the particular BP motor this thread is discussing- the crank is a cast crank and the lifters are not roller so they are limiting the revs to I think 5500. I guess you can get away with that cam whereas tougher applications are going to require the bigger cam.

Re: My experience with Blueprint engines

So I guess I should say that I am sorry! I got the engine tuned in August of 2012 and it has been running great ever since! I had an issue with my Holley Avenger had an issue with the accelerator pump nozzle being plugged! I was pretty shocked about that! I don't think the 770 is a good match for this engine IMHO. I went and bought a 670 and was much happier with the engines performance. (Especially after unclogging the squirter!) The engine has performed flawlessly ever since. It starts up with no issues and sounds great. After two years of experience with BP engines my final verdict is that I will buy from them again. I hope this helps someone in the future. See you in the forums.

Re: My experience with Blueprint engines

Bump - any updates on the engines?
I am about to pull the trigger on a BP38313CTC1, but before I do, I would like to know if they are still running strong as day one. How many miles on the engine today?

Re: My experience with Blueprint engines

My update on my 383 is that it runs awesome, is very strong and I love it.

My issue was a Holley 675 Avenger with a porous casting--I swapped carbs and this motor is a screamer (in a good way).

Arrow Re: My experience with Blueprint engines

I have read this thread as I am soon wanting to buy a crate
Engine although many of my buddys disagree and believe building it your self
Is the only true way of assuring your self the amount of money you invest
Is protected because you know how it was built.
I do have some other friends that with in the last 5 to 8 years have bought
540 merlins and they are very pleased with them I'm not sure where
They bought them but if I remember correctly they were getting something
Like 700 plus on the hp and the cost was less than 8k

At anyrate let me ask this question if your buying a motor and I am
Looking at buying from blueprint just
don't like the fact that I can't walk through thier door or any business door
Door that's not in my town but when you buy a crate motor and its dynoed
Doesnt that mean that all the tuning is good to go? My thought about
Buying a dynoed crate motor is that when she gets home you put it
In the car and it better fire right up. So my thought is why are so many people
Talking about tuning issues

I Never Said I Was The Fastest I Just Said Your Not Getting In Front Of Me
