So it seems there is very little information out there about the Avenger heads, they seem to be chinese heads previously modelled on ProComps if the info ive found is correct?
Has anyone ever used or seen anyone who has used them?
I was looking at speccing up an engine myself but have seen one advertised with the below spec for a reasonable price.
ford 302 based 347 stroke long block, 302 prepped roller block, 4.030 bore x 3.400 stroke, RPM 4340 forged crankshaft and H beam connecting rods, JE forged 10:8.1 compression, Avenger 205 CNC aluminum heads with Manley 2.05 x 1.60 stainless steel valves, heads flow 315 @ .700 intake / 235 @ .700 exhaust, Pacific 1.460 dual valve springs, Parker funnel web aluminum intake manifold, Comp Cams., .625 lift, 242 @ .050 lift, PRW 1.7 ratio stainless steel roller rockers, 7 quart oil pan, sfi balancer, dual roller timing chain, call for details, makes approx. 500hp @ 6200 rpm / 440 tq @ 4500 rpm
Otherwise i was thinking of building either a 347 engine or going all out with a 363 with the below specs:
Scat 9000 3.400 crank for the 347 or RPM 4340 internal balanced for the 363 with Dart block
Scat lightweight 4340 i beams
Manley flat top pistons for 10.7:1 CR
AFR 195 renegade heads
1.6 or 1.7 rockers dependant on lift.
Custom cam
Parts wise i can buy the above (Excluding block on the 363) for the same price as the complete built engine advertised above. Idea for the build is high 400's for the 347 and above 500 for the 363 with the best torque curve and drivability possible. Will be utilising Jim Inglese 8 stack with emerald ECU as it stands currently. Its not a no budget build so if money can be saved where it can then i want to! I don't want to end up with c##p though because i chose to save a few £'s.
Thoughts appreciated!
