My motor shop dislikes the 598 short deck motor he just doesnt think they will last.

Ya I don't know anyone that has a 598 short deck,never heard any feedback yet,they're new. I don't want to spend 10 or 12 grand and find out she'll fly apart. I guess I should phone the shops that build them and see what they have to say. I know Dynoflo and Shafiroff builds them anyone else?

Here is a thread about Dynoflo engines. It also contains another thread about them also. Just read the threads and make up your own mind on them.

:shock: here we go again.. :lol: :lol:

For a street motor I would stay with a 548. Mostly because it is a very cheap ( and good) big cube buildup. And It makes a ton of HP and torque.

4.25 Stroke 4.530 Bore with 6.385 Rod .. very popular motor in drag racing, they seem to make very good power and it'll be one bad ass street car with that motor in there.


My thoughts on crank and rods ... I run 1000hp on motor and will spray upto 300 with the spray, Eagle has worked good, I now have K1 Rods just to try them, and have good luck so far. I had a 548 once .. it made 850hp (950 on some dynos) with 10:1 compression until it broke a oliver no bearing wear just flat broke the rod in half but the callies magnum crank went with it along with the rest of the motor. Back to eagle for me ... no matter what you use, its only as good as the machine shop doing it for ya

My old 511ci and your 540ci Tod ran very similiar..almost same engines. yours had a little more Bore..non the less..they are stout running motor's...not something i would try a long day on the road with the family.

My Best ET with that 511ci was a 5.82et full street trim @3200 lbs..NO NOS all motor.

Tod you put a 300 shot on that 540ci and watch her holler.... :shock:


below is my 1st 5.99 pass in street trim....yeeee...ha.....the next clip is thanking My Northern pitcrew Tom Mc dunnah,,,lol

Give ME a 300 shot and You can watch me holler while I pick up pieces of piston off the track...

I know you used to drive that camaro on the road...can't imagine you do too much of that if any with the nova...do you ever miss having a "hot rod" to cruise to the local Sonic or whatever?
