Motor Blown, What Next?

Loanshark · Oct 12, 2014

Well I installed new injectors Wednesday on the Camaro. Unfortunately one of the injectors was faulty and stuck open which hydrolocked my motor and ended up blowing it.

Luckily, it happened right as the season was ending. This will give me to time to get the car ready for next season. It is important to me to make sure the car is running come April.

I want opinions on what to do next. I am not looking to break the banks, since I am in the middle of closing on a new house, which will add to my monthly expenses.

Car has an LS1 in it with a cam and full bolt ons. I would like to keep it a street driven vehicle that can still have fun on the track when I want it to.

Speed has done the majority of the work on the car, and I am very happy with them, most likely the car will go to them to be completed over the winter.

What would you do in this situation?

I guess the real question is what do you mean by "blown"? If you can get away with replacing a single piston and rod I'd say just do that. But if you threw a rod through the side of the block that's a different story

Possibly buy a used engine...... Or if the heads we're not damaged. Check out schwanke short blocks online. They built 2 iron short blocks for me for like 1800 dollars or so. Forged Pistons. Fully balanced and blue printed. Both engines are still going strong. 1 is in a heads cam Camaro. The other is in a mid 500 hp supercharged gto. For the price can't beat it

Not really sure the extent of the damage, but if the motor is going to be out I am sure I should get it built and do it right. The motor had almost 150k on it.

Thanks, I'll check that out.

Right now Speed is quoting me aprox. between 4k-5k to rebuild my current motor with forged pistons etc. I am not that handy around a car, and not sure exactly what I should be doing in my situation.

LT4 swap or maybe LS9. go big or go home.

Gone_2022 · Oct 12, 2014

I would recommend iron block. Your going to need that down the road anyway just do it now. With a set of solid mounts

Ha! I would like to stay around 4-5k on this. I need to hide anything I spend from the wife.

If 4-5k is your budget that is amazing. Basically anything is at ur fingertips as far as a built block goes. Texas speed has tons. That's where speed gets most of their stuff

That's probably the smartest decision. What would my full build price be aprox. with removing what I have and installing this?

If your heads arnt damaged... Well then if you forged the rods along with the Pistons I believe around 2200 or so from schwanke. If you need heads just look around for a good set of 243's

I actually have a set of 243 heads sitting in my warehouse at my office, that have not been installed yet.

How much less power will that have than my current motor? I'm really not interested in doing forced induction right now and don't want to loose power if I'm running motor only.

You should not have any power loss. That is a 5.3 bored and stroked to a 5.7. So it is the same as you have now. It has an ls1 rotating assembly

Awesome, thank you!

No worries let me know if you have any other questions

I have ton's, ha ha.

Can I put my cam that is in my car right now in this? What else will I need to end up buying to get the car up and running? Should I have Speed install it or a regular shop?

Gone_2022 · Oct 12, 2014

The engine is not that hard to pull out the top yourself. If the cam was not damaged you can put it in. First thing would be to tear down this current engine. Know the extent of your damage first before ordering parts. At the very least since your in there already. Replace the lifter trays, lifters to ls7 lifter, and get hardend push rods

90% of our engines are built by our exclusive engine builder.

Matt, we will figure this out. I think using your existing block and doing a Wiseco piston/eagle rod combo will be your best bet.

Loanshark · Oct 12, 2014

[MENTION=3559]School Boy[/MENTION], you know Speed will be doing the work on my car in the end. Reliability and trust of the builder is the most important thing to me.

Loanshark · Oct 12, 2014

Plus I don't have the know how to pull my own motor.

Gone_2022 · Oct 12, 2014

Pull out radiator. Take off accessories and put them to the side. Remove transmission. Remove both large engine mount bolts on each side. Attach engine hoist to each head and lift out carefully
