Found a dynojet only 3.5 miles by my house and took my new build to see what it was putting out.
4 Foxbody Builds at Once!
Car had 3.7 miles on it when I got to the dyno with no WOT time so I had my fingers crossed.
This car was built to be a daily driver for my wife and thus had to idle well and have no bucking issues. Max HP was NOT the goal but I did want it to be sporty. On the drive there I had it in 5th gear at 1000rpm and no bucking so I was happy with that.
Overall I am happy with the numbers (360 HP and 385 TQ) so I am not looking to do any big changes but I would rather see HP equal to torque. I am guessing the restrictions from achieving this are on the intake side which include:
70 mm TB
11.8 : 1 AFR
Stock air box
I was thinking of going to:
What I am wondering is how much of a difference do you think the first three would make and then how much more adding 1.7s.
Also, how much do you think is available in the tune. Timing was 13 deg spout out and AFR logged at 11.8:1 so there is definitely some easy HP on the table by leaning it out.
Here's the combo;
cam with .512 int .536 exh
Freshened1968 302 (C80E) bored .060 over with 347 stroker kit equals 352 cubic inch.
Eagle I beam forged rods, Forged crank 28oz balance, forged SRP pistons
Edelbrock vic jr 60cc heads ported to a 1262 with ARP head studs and FelPro 1011-1 head gaskets
7 quart oil pan
Comp Cams Link bar lifters
Professional Products SFI balancer and spacer
Holley systemax intake plenum
70mm throttle body/spacer
80mm C&L MAF
long tubes headers to flowmaster (no cats)
The weird dip at low RPM is the run when I disconnected the stock airbox and put on a conical filter. The C&L did not like that as it went from 11.8 with the stock box to 14.3 AFR and was really lean (17 -18 AFR) in that area. Guessing airflow disturbance.
