While two of their rivals failed to field teams in Midlands 4 West South, head coach Lee Maddison overcame no less than eight enforced changes to keep his side in second position, and prove rugby is far from dead in the local area.
Debutant outside centre Dave Morris nearly made the perfect start when he collected midfield partner Aaron Willis' offload only to be stopped tantalizingly close to the line.
Restored to the starting line up after a three month injury lay-off, flanker Sam Haslam burrowed over from close range to open the scoring from the resulting ruck.
Second row Michael Kemp, who enjoyed a productive afternoon, kicked the first of his three conversions in the absence of a recognised goalkicker.
Exiles hit back with a penalty kick as Park were caught handling on the floor, reducing the deficit to four.
Winger Adam Jardine went close to scoring twice in quick succession, firstly being bundled into touch and then spilling over the line after a fine despairing tackle.
But Park were not denied for long, Willis again combined well with Morris who raced over the line for a converted try.
Park were without their first choice half back pairing but Gary Lakin and Gareth Bennettp both stepped up to the mark with fantastic displays.
Lakin at scrum half was martialing his pack well, on 25 minutes he picked from a scrum drifting open before drawing a tackle and releasing Willis who cut an unstoppable path to the line.
Matt Marston and Glynn Huskins were withdrawn giving Nathan Steel and Martin Checkley game time.
Although Exiles countered with intent, they came up against a turn over hungry park Pack with prop Adam Lawrence joining the back row of Haslam, Gareth Hammond and Steel in reducing their visitors to scraps of possession.
Hooker Lee Critchlow and Willis were both adjuded held up as Park went in search of a fourth try and an ill important bonus point, but they had to be content with a 19-3 lead at the interval.
With the wind, slope and sun to their advantage, the home side cut loose in the second half scoring five more tries.
The forwards huge effort at scrum time and the break down gave Bennett opportunities to deploy a clever kicking game which kept Exiles penned back in their own half.
Each kick was chased with urgency, with Steel often leading the charge.
The bonus point try came when Critchlow finished from close range with a two man overlap.
Matt Marston was next over the line after good work from Kemp, passing infield for Park's captain's first try of the season.
Having put in a sterling shift of breakdown work and support play, prop Lawrence was the next forward to find himself outwide to finish off a move after good hands from Marston and Bennett.
Park's last two tries both came from bulldozing play from Aaron Willis from close range situations to earn himself a hattrick.
The win was Manor's biggest of the season and keeps them second, eight points behind leaders Ledbury with a game in hand.
The win also extended the homeside's perfect home record this season.
Next up for Maddison's men is a trip to Atherstone in a fortnight's time.
