Roush 427sr-tw or 427r?

Here's a couple more threads from over on the GT40s Forum:

I purchased my Backdraft R3 Roadster new in year 2015 with a Roush engine (427R dyno tested at 550 HP and 528 FT-LBS Torque) and a Tremec T56 6-speed tranny. I have driven the vehicle for a year and a half and have observed no engine leaks and only slight bucking at lower RPMs (below 1800). I have no oil burning problem--the dipstick showed no measurable loss in oil after the first 1000 miles and no measurable loss since. I live in the Phoenix and have not incurred any heat problems while driving in the hot summer heat (well over 100 F). I must say that I am quite pleased with the Roush powerplant in my Backdraft Roadster. I guess I got a good engine. Sorry to hear about all the 'nightmare' problems with other Roush engine owners.

Either there are more emotional buyers keeping the price up or is the Roush name hold a constant resale value???

Just thinking out like loud and open to thoughtful feedback. Subject parameters might be too broad for a solid answer. Thanks for the info👍

While I'm not a fan per say, I don't believe it negatively impacts resale price.
Yeah, yeah I know, I (like FR65) would be less inclined to purchase if it had a Roush engine, but it wouldn't stop me, everything is fixable in these cars, and if the rest of the package is right, and the price is right, well I wouldn't cut my nose to spite my face

I dare say the majority of joe public may see the Roush name as a plus. Why? Marketing, branding and pretty packaging. Further, they're likely to be unaware and/or are poorly researched to suspect otherwise. See links in RK's posts for example.

If you are acquiring a BDR roller (nice cars by the way), have you considered a coyote engine?
Or even having a custom engine built for you to your specifications? (Note: this is different to a create engine).
Or are you purchasing a complete car in the 2nd hand market (ie: between two cars, with one of each engine you are requesting info about)?

PS: I'm happy (and relieved) for those who have had positive experiences.
I've no doubt that even the best engine builders will make an occasional lemon, sh!t happens, no one is perfect.
But it's how they handle it there after that separates the good, from the bad.

Either way, best wishes and good luck in your hunt!

I'm a bit old school, meaning....studied the coyote engine and it's a great motor, but it has too many parts and other things that this old dog (me) don't really want to learn new tricks. Just not for me. Give me a carb a other simple things and I'll make it work good enough to make me smile. Cheers and thanks for the happy hunting!

I have the Roush 402R (got it in 2007). It does not leak oil and I have had no mechanical issues. It does buck some if it gets much below 2000 rpm. In that case I drop down a gear and problem solved. I can only speak from my experience but I would gladly purchase another Roush engine in a heartbeat.

I think the problems were more with their FE lineup.
