How good are their motors

kaos420

I have there 355 set up been running it for 3/4 yrs not a problem at all.a buddy is running the same motor an also has no problem.called there costumer service line an it was easy an they where great to deal with..

SketchyZed

okay just curious i found a 350 motor from them https://blueprintengines.com/collect...er-cam-1pc-rms does anyone have it, if so how is it with tpi?

You'd need a vortec TPI base obviously, and that 110 LSA may be a little tight for a TPI. Definitely would require a custom tune....but then....anything short of stock will as well. If it were ME......I'd look at an L31/L31R vortec crate from GM, and choose the cam you want.

Probably be about the same money when all is said and done. If ya go GM, you'd have to account for the lift if you go over .480 "ish". ....it's fairly similar money, but I'd want to pick my cam for one, but second, I'd deal with Summit and GM ANY DAY over BluePrint.

I run a tpi system on my no problems

I'm sure. No reason you can't. As for cam specs, I just made a recommendation that the LSA (110) may not be ideal, if given the choice. Not saying it wouldn't work.

As for a GM crate vs. a BP crate - I've never owned either. Wouldn't be fair for me to say. I AM however, and expert at research. Maybe the OP could just google the topic and see what comes up.

I found a cam heads everything i would need to make it work in my favor im just trying to figure out my intake im going with hsr but the heads i want are vortec and the intake is the cheaper non vortec one, should i just find different heads or just save up.

Also should i just build up my motor to a boosted 383 with hsr or wait for it to kick the bucket then buy a new motor and build that one up, of course in the meantime i would be building up the trans putting new gears and a new rearend if i can find a good deal on one.

LOT of options out there! What's the condition of the motor you have now? ...and if it's doing well, what are your reasons for replacing it?

What are your overall goals?

As for me, I went with the idea of picking certain parts first, and building OTHER parts to suit. I KNEW I wanted to keep the TPI, but wanted a substantial performance boost over my cammed L98. That meant a high flow TPI, which meant some extra money and some time to port. It also meant cubic inches, so i chose a 383. A 383/TPI is gonna be a low RPM torque monster so I chose an efficient, yet relatively small head. 180cc. Get that low RPM air velocity, sacrifice high RPM peak HP numbers. ...and of course, a cam spec'd to pull it all together. Fast ramps, moderate duration, as much lift as i could given the other specs. ....regardless of what you choose, build it as even a so-so thought out system and it'll out perform a bunch of mismatched hi-po parts.

I'd start with Budget. Then what you realistically want. Then figure out the best way to get there. I did my cam and exhaust right after retiring my car from DD duty, but it was another 10 years, a wife, and a HOUSE before I was finally able to the build my current motor/trans combo. It takes time and planning. Don't rush it. Well....RUSH it...sure....but I mean....you know, lol.

SketchyZed

I'm taking my time I am in no rush to do this I just like having a plan set for things like is. The motor is an l98 when I first got the car it had 74k on it and now I'm at 94k and the reason why I'm thinking of replacing it is I think there might be better things out there you know have a brand new motor compared to building what might be a worn out one, and as for goals my end goal is 500hp after I put a procherger on it
So n/a I'm thinking 435 or 450 hp building it to a 383 with hsr

SketchyZed

Do you think I should build my l98 up or just buy a new 350 from blueprints

Look at what Abubaca done in his build first- excellent IMO still retaining the great looking and time period TPI system. Have your L98 bored. Buy a stroker kit rotating assembly and some good heads.. If you have the time and patience. As for the BluePrint engine pretty much all you would need is yours rebuilt with an Alex spring kit for a set of Vortec heads and a good cam and you are right there.

THANKS!

If you have the time AND....a shop you trust, i say building your current L98 is the way to go for sure. Especially if you're gonna supercharge it later. Spend the money where you need it, save money where you can. Given your goal of 500, and your plan to supercharge....have you considered an LS swap? You could get to 500 hp a LOT cheaper. Yes, you'll have costs associated with the swap, but not much wouldn't have to be swapped anyway. Trans, rear, fueling system...all gotta go to hold 500hp, regardless of what kind of motor it is.

EDIT-My point being that you can make 500 with an LS easily, and NOT have to spend money on the supercharger

My goal was to keep the TPI, but while researching, I actually changed my mind and bought an 6.0 liter LQ9. Started accumulating parts, and read the How to build an LS engine book cover to cover twice. At the end of the day.....had to keep TPI. I sold the LS. .....but unless you have a good reason, and there are good reasons obviously, but unless you have one......egad, hard to steer you away from an LS.

SketchyZed

i have a plan to rebuild my trans and to make my car handle it, and yes i have looked at ls swaps but i heard its not the swap that kills you its all the little things you need and i asked some people what i should do they said i could have a built sbc for the same price as a 5.7 ls out of a camaro/bird depending on the donor vehicle and how complete it is. I want to keep my old sbc because the aftermarket it so plentiful and you don't really see them anymore people are usually drop in an ls now, yes i know its the better motor but the old sbc has this charm to it.

P.S I also heard that ls parts can be expansive

Abubaca

Plenty of good reasons to go with either, and it comes down to many different factors. ...and I completely agree with the charm of the SBC!!!!!!!

dmccain

iTrader: (2)

I prefer the old SBC in these old cars myself.

SketchyZed

So you think 430hp or 450hp is do able with a 383 or even a 355 with a hsr naturally aspirated?

SketchyZed

What I'm thinking about doing is get summit's vortec heads getting hsr then porting them save up for the cam and the rotating assembly to make it a 383, well before all that put 3.42 gears in the rear build up the trans get better fuel system and ecm

Is the ultimate goal still to supercharge? I'm not an expert, but from what I know, the ideal specs for an n/a motor and a supercharged motor are way different. You're either gonna sacrifice power now, on the n/a motor, or on the blown motor later. Can't have your cake and eat it too.

As for heads, if you're going vortec, look into the Chevy Vortec Bowties. You've got some big port options right outta the box. 19331472 - 225cc or 19331470 - 185cc.

All that being said....I LOVE vortec heads.....but I think you need better. Don't skimp on heads. I went with RHS, for several reasons, but take a look at the Pro-filer All Americans. They're a great head AND a good price. I think they're a 1206 intake gasket, and even though I've ported my stock TPI base out to a 1205, there isn't enough material to seal to a 1206. That's why I went another route myself.

SketchyZed

im gonna sacrifice for now n/a i just need that power to be mid 300hp to mid 400hp if possible, then later down the road i buy the procharger. Im trying to make so i can still run my motor on pump gas which is why i don't want too high of a compression ratio, so when i was looking for heads i looked at gm vortec heads and summit racing 72cc heads i found some 67cc vortech heads i thought that would have been the best of both worlds.

Do you think i can make it just to 350hp or 430hp just with heads, cam, and the hsr intake?

Abubaca

Yeah, that's totally do-able.

If supercharging is definitely the goal, I'd jump on over to the power adder forum, and go from there. Once you have a good idea on the proper heads and cam that'll go with the supercharger, see where you're at n/a. See if you're at your power goal n/a. Even a cam is a relatively cheap and easy swap awhile down the road.

Okay thank you
