Ok Jim ,here is a thought from an very cheap amature. But I have the stats and timeslips to prove it.
Take one CR with a bone stock 302, 200 hp fresh block ,running A/C and power steering ,355 gears to the track. Everyone else is running 11's and 12's and your holding a 15.01 slip. Best of the day there were worse.

Now go home tell wife , other boys kicked sand in my face I have to pull the motor. REPLY --- Wait for it------
I DON'T HAVE A NEW KITCHEN ,NEW BATH,NEW,NEW,NEW NEW NEW ANYTHING AND YOUR GONNA PULL A PERFECTLY GOOD MOTOR. HOW ABOUT I GET A NEW HUSBAND.

Or words to that effect. Ok drop back and punt.You say I can't pull a good working motor ,but what if it breaks. I know you can see this coming.

Can you say Edlebrock Nitrous carb set up with the 150 hp jets. I have heard all the horror stories so I figure I can screw this motor up quickly. Leave it to me ,it gets installed perfectly I run about twelve bottles through this motor tearing the guts out of it and it won't quit.It also runs 13.01 which I consider real respectable considering I only spent about 450 including the install. And the sound when the micro switch hits the gas flow is scary. Sounds like demons from hell . I can't believe this motor won't come apart as hard as I tried. Finall had to sell when a 351 dropped in my lap. This also has the bottle on it but I pulled the jets back. I dyno'd about 387 at the flywheel so the juice on top is just scary.
